The admission to a local fair is $10 for each adult and $6 for each child. each ride costs $1.50 for an adult and $1 for a child. a. write an expression that represents how much more an adult will spend at the fair. b. an adult and a child each go on 7 rides. how much more did the adult spend? ! this is part of my homework that is due

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

The answer is something i don’t know
