Question

Answer 1

Billy must mow at least 14 yards

Answer 2

Inequality:
`15x\geq 200`

x=14

Explanation:

Billy charges $15 to mow a yard.

Billy charges $15 to mow a yard. He needs at least $200 for the new bicycle that he wants.

Let he bought x number of mow

Cost of each mow = $15

Cost of x number of mow = 15x

He had atleast $200

15x should be greater than 200

Inequality form:

`15x\geq 200`

Now we solve for x

`x\geq 13.33`

He should buy atleast 14 mow.

Hence, 14 yards must he mow to make $200
