Answer: x=3
Step-by-step explanation:
7(8-x)=56-21
56-7x=35
-56 -56 (subtract 56 from both sides)
-7x=-21
/-7 /-7 (divide each side by -7)
x=3
Alto earned $ 225 and Sheryl earned $ 250.
Given that Alto and Sheryl both worked hard over the summer, and together they earned a total of $ 475, and Sheryl earned $ 25 more than Alto, the following calculation must be performed to determine how much each one earned:
- S = A + 25
- A = A
- A + 25 + A = 475
- 2A = 475 - 25
- A = 450/2
- A = 225
- S = 225 + 25 = 250
Therefore, Alto earned $ 225 and Sheryl earned $ 250.
