Question

A game of mini golf costs $2 per round and has a $11 entry fee for an adult, and costs $5 per round and a $5 entry fee for a child. For how many rounds of golf are the costs the same for an adult and child?

Answer 1

2 rounds

Explanation:

Let's say the number of rounds of golf is x

That would mean an adult would cost 2x+11

And a child would cost 5x+5

The equation would look like this:

5x+5=2x+11

3x+5=11

3x=6

x=2

So 2 rounds before the cost between child and adult is equal.
