Answer 1

3

Explanation:

Answer 2

x
`\leq` 6

Explanation:

First, set up expressions to represent the costs of both gyms, where x is the number of fitness classes:

Lazy Gym can be represented by 10x + 30

Get Abs Gym can be represented by 15x

Then, create an inequality equation to represent the situation. Since we are trying to find when Get Abs Gym is cheaper than or equal to Lazy Gym, we will use a less than or equal to sign:

15x
`\leq` 10x + 30

Then, solve for x:

15x
`\leq` 10x + 30

5x
`\leq` 30

x
`\leq` 6

So, at 6 fitness classes, the prices will be the same. For more than 6 fitness classes, Get Abs Gym will be cheaper than Lazy Gym.
