Exercise 8 Page 167

Let f( x) be the amount of money needed for x days. In this case the amount of money can be found by multiplying the budget of $65 per day by the number of days. f( x)= 65 x Note that 2 weeks is 14 days. By substituting 14 for x in the function, we can find the amount of money needed for 14 days.

f(x)=65x

Substitute

x= 65

f( 14)=65( 14)

Multiply

Multiply

f(14)=910

Marla would spend $910 on a 2 week business trip.
