Answer:

1) His total commission is $1,234.3

2) The purchase of the car is $24,790.

1) 21640*0.02=432.8+250=682.8

15075 0.02301.5+ 250-551.5

682.8+ 551.5-1,234.3

2) 745.8-250-495.8/0.02= 24,790

Step-by-step explanation:

don't guess around, just calculate yourself.

first he sold a car for $15,075.

c(15075) = 250 + 0.02×15075 = $551.50

then he sold another car for $21,640.

c(21640) = 250 + 0.02×21640 = $682.80

his total commission was

$551.50 + $682.80 = $1,234.30

c(p) = 745.80

what was p ?

745.8 = 250 + 0.02p

495.8 = 0.02p

p = 495.8/0.02 = $24,790
