Question

Joel is looking at costs for using a gym. He could pay $50 per month for unlimited use or he could pay $12 per month plus $4 per visit. How many visits would he have to make each month to make the $50 per month unlimited use option the cheapest one?

Answer 1

`y = 4x + 12`
Joel would have to go at least 10 times per month to make the 50 dollars per month the cheapest one.

Answer 2

First choice is cheaper.

Explanation:

Joel could pay $50 per month for unlimited use or he could pay $12 per month plus $4 per visit.

Let the monthly visits be x

We can define this as :

`12+4x> 50`

`4x >50-12`

`4x >38`

`x> 9.5`

So, x can be greater than 9.5 means 10.

`4(10)+12>50`

`52 > 50`

Comparing both we can say that the first choice is cheaper.
