Answer:
18
Step-by-step explanation:
3+9=12
12/2=6
6x3=18
64 because each apple is sliced into 8ths and there are 8 apples so 8x8=64
Let number of hours needed to work = x
Multiply number of hours by rate: 15x
Add what you already have saved:
15x + 215
This needs to equal at least 800:
The equation becomes:
15x + 215 >= 800
Solve for x:
15x + 215 >= 800
Subtract 215 from both sides
15x >= 585
Divide both sides by 15
X >= 39
They have to work at least 39 hours.
