Find the total cost with tip.

Markup (tip $) = percent markup (tip %) x original cost ($)

Total cost = original cost + tip


Mr. Smith goes out to eat for his birthday. The total bill is $122.50. If Mr. Smith leaves a 20% tip, what is the tip amount? What is the total cost of the meal with tip included?

The tip is: $_________

The total cost of the meal is: $_________

Answers

Answer:

$147

Step-by-step explanation:

so to find 20% I usually divide the original cost by 100 to get 1% then multiply that number by 20.

in this case 122.50/100= 1.225, 1.225x20 = 24.5

24.5 + 122.50 = 147

Question 1
A truck driver drove 48 miles in 45 minutes. At this rate, how many miles can the truck driver drive in one hour?



__ miles in one hour
pls no links ty

Answers

The truck driver can drive 64 miles in one hour.

Distance covered by the truck driver in 45 minutes = 48 miles

Distance covered by the truck driver in 1 minute = [tex]\frac{48}{45}[/tex]

                                                                                 = 1.066 miles

Distance covered by the truck driver in 1 hour i.e. 60 minutes = 60 × 1.066

                                                                                                      = 63.96

                                                                                                      ≈ 64 miles

Therefore, the distance covered by the truck driver in 1 hour is 64 miles.

Answer:

x > 6

Step-by-step explanation:

Solve -2x <-12 for x.  Your answer must be a set of real numbers.

Divide both sides by -2.  Note that if we here divide by a negative number, we must reverse the direction of the inequality symbol:

-2x < - 12

-7 – 2 =

-8(-6) =

18/-3=

Answers

Answer:

-5 , 8 , 48 , -6

Step-by-step explanation:

-7- -2 = -5

This complies with the rule that 2 negatives make a positive.

12 + (-4) = 8

You just ignore the brackets.

-8(-6) = 48

The -8 next to the bracket with no symbol means you need to multiply, and again 2 negatives make a positive.

18/-3 = -6

As the 18 is not negative, but -3 is, the answer is also a negative because one negative and one positive make a negative!

Hope this helps and have a good day!

Slope is defined as rise/run. Specifically, ((y2 - y1)/x2 - x1))- To define slope, we read the graph from right to left. Pick two points on the graph. I’ll pick the following two points:

(-2,13) and (0,5)

Applying the above formula will get you ((13-5)/(-2-0)) = 8/-2= -4
-4 is the slope

The y-intercept is the y-value where the line crosses the y axis. In this function, the y-intercept is 5.

The slope intercept form can be written in the form: y = mx + b where m is the slope and b is the y-intercept. Therefore, substitution of the values we’ve got will give us the following answer:

y = -4x + 5

The mark down is 30% so we need to find how much that is then add it to the price it is now.

30% of 327 = 98.1

So there are numbers that can be reduced like 3 divided by 6 and 38 divided by 2. So now that there are simpler nmbers that cannot be reduced more we multiply and we get 19/2 which if you wanted as a mixed fraction is 9 and 1/2.

Jose goes out to lunch. The bill, before tax and tip, was $10.45. A sales tax of 8% was added on. Jose tipped 17% on the amount after the sales tax was added. What was the total cost of the meal, plus tax and tip? Round to the nearest cent.

Answers

$13.20 $10.45x1.08=$11.28 $11.28x1.17=$13.20
ANSWER: $13.21

Find 8% of 10.45 then add the answer to 10.45 to get how much it cost after the sales tax.

8% of 10.45 = 0.836

Add 0.84 to 10.45

The answer is 11.29

Now take 17% of 11.29 and add it to 11.29. We are taking 17% of 11.29 because it said he tipped after the sales tax was added.

17% of 11.29 = 1.92

11.29 + 1.92 = 13.21

$8 x 70hours = $560

(8 x 7 = 56 x 10 = 560)

Next, work out the commision.

10% of $1612

1612 ÷ 10 = 161.2

Finally, add together both the hourly wages and commision.

161.2 + 560 = 721.2

Round it down to a whole number.

The arrow went under his left armpit . . . a wound that would have been quickly fatal and probably not treatable even in modern times, especially where it happened. By the angle of the wound, he was either shot from below and behind, or he had been bent forward when he was hit from above and behind.
