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.
Answer:
$516
Step-by-step explanation:
first you multiply 12 and 25 and you get 300
then you multiply 12 and 18 and you get 216
Then finally you add 216 and 300 together to get $516
3.14 x 9^2 x 14/3 = 1186.92
4/3 x 3.14 x 9^3 = 1526.04
1186.92 + 1526.04 = 2712.96 = 2713 cubic inches
