Answer:
We have the constraint 12x + 8y = 1800 to solve
x and y both have to be positive (she can't work negative hours)
If we choose x = 100 then we have 1200 + 8y = 1800
8y = 1800 - 1200 = 600
y = 75
We know this works because 12 * 100 + 75 * 8 = 1800 which is what she needs.
The answer is -0.42 because -100% is -1 and -1 + .58 is -0.42

Step-by-step explanation:
Your question isn't complete but let me help out. The value of each shirt will be gotten by subtracting $47.15 from the total amount paid for the shirt and jacket. Let's say the total amount paid is $90.02
Since the jacket cost $47.15, the cost of the shirts will be:
= $90.02 - $47.15
= $42.87
We would now divide the coat if the three shirts by 3. This will be:
= $42.87 ÷ 3
= $14.29
