Question

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.

Answer 1

11.

Explanation:

I got the answer of 11, as I:

-First, I worked out how many rides Margaret would be able to go on, so I did $35 -/- $3, which was a decimal, but the most amount of times would be 11 rides that she could go on, therefore, that's the amount of rides she would take, and have $2 left over.

Hope this helps!

Answer 2

3r = 35

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 =
`(35)/(3)`

r =
`11(2)/(3)`

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

So she has left $2.00 with her.
