Answer:
See below.
Step-by-step explanation:
Let's look at the cost for members (C1) first. Let x be the number of visits.
C1(x) = 12 + 8x
For non-members (C2), we can do the same.
C2(x) = 10x
You can graph these two equations.
x C1 C2
0 12 0
1 20 10
2 28 20
3 36 30
4 44 40
5 52 50
6 60 60
7 68 70
Let's make the two equations equal, to find out where the benefit is the same.
12 + 8x = 10x
2x = 12
x = 6
Up to 5 visits, the non-member cost is better. At 6 visits, there's the same price. For more than 6 visits, the member cost is better.
If you are looking for the average speed, it is 2m/1 sec.

Answer:
First deposit - Same amount
Second deposit - Sylvia
Third deposit - Sylvia
Step-by-step explanation:
Leroi put $200 in their account. They will add $40 every week.
Deposit 1: $240
Deposit 2: $280
Deposit 3: $320
Sylvia put $200 in their account. They will add 20% of the amount in the account each week.
Deposit 1: $240 (20% of $200 is $40)
Deposit 2: $288 (20% of $240 is $48)
Deposit 3: $345.60 (20% of $288 is $57.60)
So, Sylvia and Leroi have the same amount of money in their accounts after the first deposit. After the second and third deposit, Sylvia has more money.
