Denise is going to the county fair this weekend. The admission to the fair is $5 and the cost per ride is $0.50. If her parents gave her $20, write and solve a linear equation to find how many rides she can go on.
Ok first you have to subtract 5 because you payed 5$ to get in and then you divide 15$ by 0.50 and that will give you 30. So she can ride 30 rides total!
