Answers
50 oz. of 12% sugar and 30 oz. of 20% sugar is needed to produce 80 oz. of 15% sugar.
EquationAn equation is an expression used to show the relationship between two or more numbers and variables.
Let x represent the amount of 12% sugar and y represent the amount of 20% sugar need to produce 80 oz. of 15% sugar. Hence:
x + y = 80 (1)
Also:
0.12x + 0.2y = 0.15(80) (2)
From both equations:
x = 50, y = 30
50 oz. of 12% sugar and 30 oz. of 20% sugar is needed to produce 80 oz. of 15% sugar.

Solve each simple interest word problem 11) A new car volued at $28.000, depreciates of 9% per year. What is the value of the car one year after purchase?
Answers
[tex]\qquad \textit{Amount for Exponential Decay} \\\\ A=P(1 - r)^t\qquad \begin{cases} A=\textit{current amount}\\ P=\textit{initial amount}\dotfill &28000\\ r=rate\to 9\%\to \frac{9}{100}\dotfill &0.09\\ t=\textit{elapsed time}\dotfill &1 \end{cases} \\\\\\ A=28000(1-0.09)^1\implies A=28000(0.91)\implies A=25480[/tex]
Answer:
$25,480
Step-by-step explanation:
In one year, the car depreciates by 9% of its original value:
0.09 × $28,000 = $2520 . . . . amount of depreciation
The value at the end of one year is ...
$28,000 -2,520 = $25,480
The value one year after purchase is $25,480.
Consider the equation y = 3x - 1
Identify the slope and y-intercept and
sketch the graph.
Answers
If you want to find the y-intercept, you do that by putting a zero in for x, so you want to find the point that the line intersects the y-axis. So x would be zero, and wherever that point is is the y-intercept. In this case:
y = 3x - 1
y = 3(0) - 1
3 times 0 is zero
y = - 1 So, the y-intercept is - 1, or (0,-1)
To sketch the graph, you just place any number in for x or y (x is easier in this case), and solve it.
For example, I am going to say that x equals two.
y = 3(2)-1
y = 6-1
y = 5
So, your point to put on the graph would be (2,5) (x,y)

Juanita has $25, and she makes $11 per hour. She needs at least $58 to buy new shoes. Write and solve an inequality to determine how many hours Juanita must work to be able to buy new shoes. Then interpret the solution.
Answers
Answer:
Juanita must work 3 hours and above to be able to buy new shoes.
Step-by-step explanation:
Initially, Juanita has $25 and make $11 per hour
meaning, Juanita's new cash in hand after t hours is;
[tex]\tt C=25+11t[/tex]
Juanita needs at least $58 to buy new shoes;
meaning, the minimum cash Juanita should have should be $58 and above.
Simply put,
[tex]\tt C\geq 58[/tex]
[tex]---> \tt 25+11t\geq 58[/tex]
[tex]\tt --->11t\geq 58-25[/tex]
[tex]---> \tt 11t\geq 33[/tex]
[tex]----> \tt t\geq \frac{33}{11}[/tex]
[tex]---> \tt t>3[/tex]
The solution reveals that Juanita must work 3 hours and above to be able to buy new shoes.
