Kyra receives a 5% commission on every car she sells. She received a $1,325 commission on the last car she sold. What was the cost of the car?
Use the proportion part/whole = %/100 to solve the problem; $1,325 is the part and 5% is the %. We are looking for the whole so we will call it x; 1,325/x = 5/100. Cross multiply; (1,325)(100) = 5x. Divide both sides by 5 to solve for x; 132,500/5 = 5x/5; x = $26,500. If you chose b, you found 5% of her commission (5% of $1,325).
