A child asks her dad for an allowance that starts with a penny and then doubles every day for a month. Which function can be used to model the amount of money, A, the child will receive each day, x?

A(x) = 2(0.01)x

A(x) = 0.01(2)x

A(x) = 0.01(1 - 2)x

A(x) = 2(1.01)x

Write an equation that models the following situation:
Samantha's hair was known to grow very rapidly. It began at a length of 6 in and grew at a rate of 14% a week.

y=6(0.14)x

y=6(1+14)x

y=6(1.14)x

y=6(0.86)x
