Question

Natalie takes online classes at Florida State college and Orlando Community colleges. At Florida State, class fees are $118 per credit hour, and at Orlando Community, class fees are $105 per credit hour. Natalie is taking a combined total of 15 credit hours at the two schools. Suppose that she is taking "f" credit hours at Florida state. Write an expression for the combined total dollar amount she paid for her class fees.

Answer 1

The combined total dollar amount Natalie paid for her class fees can be expressed as follows:

118f + 105(15-f)

where f is the number of credit hours Natalie took at Florida State.

Simplifying the expression:

118f + 1575 - 105f

= 13f + 1575

Therefore, the combined total dollar amount Natalie paid for her class fees is $13f + $1575.
