Isaac rented a movie but forgot to return it on time. The table below shows the total amount of money that Isaac owed after different numbers of days.  Which function models the amount of money Isaac owed after x days?

• y = 1.25x + 1.75
• y = 1.25x + 3
• y = 1.25(3)^x
• y = 3(1.25)^x   

Suppose a gym charges a flat fee of $25 per month. There is an additional charge of $2 each time a person uses the pool. Which function models the monthly cost, g(x), for a person to use the gym and the pool x times?

• g(x) = 27x  
• g(x) = 27  
• g(x) = 25x + 2
• g(x) = 2x + 25

Solve:
3x + 7 = -8

• 5
• -5
• -12
• -18

The steps in solving 5b - 6 = 24 are: 

• Add 6 to both sides and divide both sides by 5
• Add 6 to both sides and multiply both sides by 5
• Subtract 6 from both sides then multiply both sides by 5
• Subtract 6 from both sides then divide both sides by 5
