Rachel must store a few pieces of her furniture for six months. a storage unit costs $55 for the first month and $47.50 for the remaining months. how much will it cost to store her furniture?

$55x$47.50(5) = $292.50
The initial cost is $55 for month 1. For the remaining 5 months it is $47.50. You have to multiply the month cost($47.50) times the amount of month you need, which is 5. Then add $55 which is the cost of the first month
