PLEASE HELP!!!! A department store's customer parking lot has 4 rows with an equal number of parking spots in each row. The lot also has 15 parking spots for store employees. If c cars can be parked in each of the 4 main rows of the parking lot, what is the expression for the maximum number of cars that can be parked in the parking lot?
a.15c − 4
b.c(15 − 4)
c.4c + 15
d.4(c + 15)

Answer 1

C cars can be parked in each rows. so total cars in 4 rows = 4 x c = 4c

including 4c, 15 additional cars can be parked. so, maximum cars that can be parked = 4c + 5.

the answer is c
