so the complement set would be
{-1,0,2,3,4) which matches with b)
Answer:
Chelsey can be a member of the fitness club for <u>10</u> months.
Step-by-step explanation:
Given:
Chelsey wants to join a fitness club.
The fitness club charges an initial membership fee of $55 and a monthly fee of $19.50.

Let the number of months Chelsey can be a member of the fitness club be 
Monthly fee = $19.50.
Membership fee = $55.
Now, to get the number of months Chelsey can be a member of the fitness club we write and solve an equation:


<em>Subtracting both sides by 55 we get:</em>

<em>Dividing both sides by 19.50 we get:</em>

Therefore, Chelsey can be a member of the fitness club for 10 months.
