So first start out by writing an expression for the cost of the child and the adult separately.

Child:
6 + 1r ($6 + $1 per ride)

Adult:
10 + 1.5r ($10 + $1.50 per ride)

to find how much more the adult will spend, just do Adult Expression - Child Expression which will be:

10 + 1.5r - (6 + 1r) just simplify this

For Part B, use your equation from part A where r = 7
