Billy charges $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?
The equation would be 15y=200. The y stands for how many yards he will have to mow. This equation will result in a number that is not whole, but you will just have to round up to the next whole number. :-)
