To rent a jet ski at Sam’s costs $25 plus $3 per hour. At Claire’s, it costs $5 plus $8 per hour.
Write a system of equations to represent each shop’s charges. DEFINE YOUR VARIABLES!
y =3x + 25
y = 8x + 5
x - The number of hours of the rental
y - The cost of the rental

When the local gym opened, it had 35 members. Each month they gained the same amount of members. They are tracking their total members using the table shown.
What is the rule for this situation?
y = 8x + 35

When the local gym opened, it had 35 members. Each month they gained the same amount of members. They are tracking their total members using the table shown.
Alyssa thinks that the gym will have 115 members in 10 months if they keep growing at this same rate.
Is she correct or incorrect? Explain in depth.
Yes, Alissa is correct that the gym will have 115 members in 10 months.
y = 8x + 35
115 = 8(10) + 35
115 = 80 + 35
115 = 115

Solve the equation for the variable
2x+2/3 = x-2/7
x = -20/21

Change this system of equations into slope intercept form.
-14 + 2x + 2y = 3x - 8
3x + 2 + y = 2x + 2
y = 1/2x + 3
y = -x

Tony and Cleo are donating some of their books to a hospital. Tony has already donated 20 books and will contribute 2 more books each month. Cleo has already donated 8 books and will contribute 4 more books each month.
After how many months will they have contributed the same number of books? How many books will they each have contributed at that time?
Find the two rules (one for Tony and one for Cleo) and solve the system of equations to find the answers.
After 6 months both Tony and Cleo will each have contributed 32 books
