Question

Ken charges his neighbors $17.00 to wash their car. How many cars must he wash next summer if his goal is to earn at least$1800?

Answer 1

Let x be the minimum number of cars Ken has to wash to reach his goal, then we can set the following linear equation:

`17x=1800.`

Solving the above equation for x, we get:

`x=(1800)/(17).`

Rounding up to the nearest whole number we get:

`x\approx106.`

Answer:

`106.`
