Tiana is building her dog a rectangular kennel that is 29 feet long, and she purchased 108 feet of fencing. She needs to know how wide the kennel should be to use all the fencing. What is the most appropriate strategy for Tiana to use to find the width of the kennel? Tiana can draw a rectangle and label two opposite sides 29 feet long, then subtract those two side values from 108 and divide the difference by 2 to find the width of the kennel. Tiana can subtract 29 from 108 to find the width of the kennel. Tiana can subtract 29 from 108, then divide the difference by 2 to find the width of the kennel. Tiana can write down the side lengths she knows and look for a pattern, then continue the pattern to find the lengths of the missing sides.

Suppose that Mario owns a company that rents moving vans. Mario’s customers pay $22$22 per day to rent a van and an additional $0.59$0.59/mi. Thus, a customer who rents a van for one day and drives it ?x miles must pay a total cost of ?=22+0.59?.C=22+0.59x. Over the last two months, Mario had 3030 customers who made one-day rentals. All together, these customers drove the vans a combined 3300 mi.3300 mi. Find the mean cost for these customers. Round the answer to the nearest cent.
