The Scott family stayed at a hotel forn nights. The cost was $80 per night plus a one-time
fee of $20 because they brought their dog. Which expression represents the total cost of
their hotel stay?
a. 80n + 20n
b. 80 + 20n
C. 80n + 20
d. 80 + 20+ n
let n represent the rate per night. hence, the total cost will be 80n+20 since the cost for the dog is a one-time fee and will not change regardless of the no. of nights stayed.
