Glenda and Fiero are at a restaurant eating meal that costs $30. They have a discount coupon that gets them 10% off the cost. If they pay the waiter a tip of 8% of their bill, how much are they spending on dinner including tip? (I ALREADY KNOW THE ANSWER. BUT I NEED THE WORK FOR THE ANSWER TO SHOW MY TEACHER) (the answer is $29.16))
The cost of meal = [tex]$30[/tex]
The tip to the waiter = [tex]8%[/tex]%
Discount = [tex]10%[/tex]%
Cost = [tex]30 + 0.08 * 30 - 0.1 * 30[/tex]
Cost = [tex]30(1 + 0.08 - 0.1)[/tex]
Cost = $[tex]$29.4[/tex]0

6. The value of a car depreciates by 22.5% per year. After how many years is
the value of the car first less than 40% of its original value
[tex]\qquad \textit{Amount for Exponential Decay} \\\\ A=P(1 - r)^t\qquad \begin{cases} A=\textit{current amount}\dotfill &\stackrel{40\%~of~P}{0.4P~~~~}\\ P=\textit{initial amount}\dotfill &P\\ r=rate\to 22.5\%\to \frac{22.5}{100}\dotfill &0.225\\ t=\textit{elapsed time}\\ \end{cases} \\\\\\ 0.4P=P(1-0.225)^t\implies \cfrac{0.4P}{P}=(1-0.225)^t\implies 0.4=0.775^t[/tex]
[tex]\log(0.4)=\log(0.775^t)\implies \log(0.4)=t\log(0.775) \\\\\\ \cfrac{\log(0.4)}{\log(0.775)}=t\implies \stackrel{\textit{about 3years, 215days and 8hrs}}{3.59\approx t}[/tex]
so at that time the value is 40% of its original value, I guess is less than that a minute or an hour later.

Answer:

Step-by-step explanation:
2x-4=y
2y+3x=13
We substitute the y in. They already gave us the equation 2x-4=y simplified so you would just plug this into the other equation
2(2x-4) +3x=13 : *distribute*
4x-8+3x=13 : *combine like terms*
7x-8=13 * add the 8 to the other side*
7x=21 *divide*
x=3
So the y=2x-4 is what we added in the place of the y to subtract it and solve for x. The second step would be solving for y. So now that we have our answer, 3 we plug it into the other equation preferably.
2(3)-4 =y : 6-4=y : 2=y
We can check our answer by pugging both x and y into both equations to make sure they are right. The statement should be true.
2x-4=y 2(3)-4=(2) 2=2
2y+3x=13 2(2)+3(3)=13 13=13

An angle measures 52° less than the measure of its complementary angle. What is the measure of each angle?
Answer:
Measure of each angle is 71 and 19 degrees.
Step-by-step explanation:
Let's the angle be "n"
Complementary angle = 90 °
n- (90-x) = 52
n - 90+ n = 52
Combine like terms
n - 90+ n = 52
2n-90=52
Add 90 to both sides of the equation
2n-90+90=52+90
simplify
2n = 142
Divide both sides of the equation by the same term
2n/2 = 142/2
Simplify
n = 71
2n = 142
Measure of each angle
1st = 71
2nd = 90-71 = 19

What is Simple Interest?Simple interest is a method for figuring out how much interest was paid on a sum of money during a specific time period at a specific rate. Simple interest has a constant principle amount. Simple interest is a clear-cut and simple method for computing financial interest.
We have,
P = $84,410.
R= 15%
T = 4 years
Using Simple Interest
SI = (P x R x T) / 100
SI = (84410 x 15 x 4)/100
SI = 5,064,000
So, the amount is
= 84,410 + 5,064,000
= 5,149,010
