This means the amount owed ininteresteach month is the output of a function,f(x)

, that uses the input of the previous month's balance,x

.

f(x)=0.01x

The new month'sbalanceis the output of a function,g(x,p,e,a)

, that use the following inputs:

• x
• , the previous month's balance
• p
• , the payment
• e
• , the expenses charged on credit for the month
• a
• , the amount owed in interest

g(x,p,e,a)=xp+e+a

Use the two functions to fill in the table below. For each question, round to the nearest penny and don't use commas or dollar signs.
