Answer: (a) $ 1,150
(b) 15%
Step-by-step explanation:
(a) The original cost of the phone is $1000
He will make a down payment of $250
Also , 6 monthly payments of $150 each, which implies : 150 x 6
= $900
Altogether , he will pay
$250 + $900 = $ 1,150
(b) Original cost of the phone is $1000
Amount Omar paid is $1,150
difference in price = $1,150 - $1000
= $150
% increase = increase / original price x 100
% increase = 150/1000 x 100
% increase = 15 %
