(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 %

1) divide 23 by 27
