Question

Jesse now has $200 and his goal is to buy a bicycle that costs $375. He earns $10 for every car that he washes. Write an inequality that represents the number of cars Jesse must wash in order to afford the bicycle. Then, solve the inequality to determine the number of cars Jesse must wash in order to afford the bicycle. Show all of your work and remember to include units.

Answer 1

Answer:

$200 + $10x = $375

Well we're going to round up to $380, cause their making money in increments of 10 rather than 5.

And based off that I'd subtract $375 from $200 (375 -200 = 180)

Then take that answer and divide it by 10. (180 / 10)

Jesse will need to wash at least 18 more cars in order to afford the bicycle

Answer 2

200 + 10x = 375
x = 17.5, but round up to 18 because you can’t wash half of a car
