Question

Billy needs $15 to mow a yard. He needs at least $200 for the new bicycle that he wants. Write and solve an inequality to find out how many yards must he mow to make at least $200?

Answer 1

x = yards mowed

15x >= 200 -- divide both sides by 15
x >= 200/15
x >= 13.33
so basically he needs to mow at least 14 full yards to make $200 or more
