Answer is D
sum of constants = 8 + 4 = 12
sum of coefficients = 7 + 3 = 10
12 > 10
8.7-10.3=1.6 you add the 2 and you give one tenth to the ones place and subtract to get your answer

We are to determine the wages that Percy receives from working in the library and the coffee cart. We are given with the system of linear equation that would be used for the calculation,
3x + 2y = 36
2x + 5y = 50
Where x and y are the wages from the library and coffee cart, respectively.
Solving for the values of the variables will give us the values of:
x = 7.5
y = 7
Therefore, the answer to this item is that Percy earns a greater hourly wage of $7.50 at the library.
Answer: x=120
Step-by-step explanation:
(2x-50)+(x+40)+150+80+(x+20)+90= 720
4x+330= 720
4x=390
x=97.5
