Your new job guarantees you an eight percent raise for each year with the company. If your initial salary is $42,200, write an equation to model your salary after t years.

• S = 42,200t^1.08

• S = 42,200^1.08t

• S = 42,200(.08)^t

• S = 42,200(1.08)^t

Max bought a new speed boat that cost of $33,000. The boat depreciates approximately 18% of its value each year. Write an equation to model the value of the speed boat.

• A = 33,000^0.18t

• A = 33,000^1.82t

• A = 33,000^0.82/t

• A = 33,000(0.82)^t

Annie is renting an apartment and sees in the rental agreement that each year they will raise the rent by 5%. The rent when she first signs the agreement is $850. What function best models the amount of rent she will have to pay in each future year?

• y = 50x + 850

• y = 850x + 50

• y = 850(1.05)^x

• y = 850(0.05)^x
