Margaret goes to the county fair with $35. rides cost $3 each. write an equation that gives the amount of money m that margaret has as a function of the number of rides r that she takes.

3r = 35

Step-by-step explanation:

Margaret goes to the country fair with $35.00

Each rides cost at the fair = $3.00

Let she can take number of rides = r

The cost of rides = 3r

She has $35 so the equation will be

3r = 35

r =  

r =  

Therefore she can take 11 rides. She spent on 11 rides 11 × 3 = $33.00

So she has left $2.00 with her.
