Question

Peter bought three Note 20 Android phones costing 1050 dollars each. If he had 4000 dollars in his checking account, write a numerical expression and then find his balance after he paid for the phones. Solution​

Answer 1

4000 - 3(1050)

= 850

Explanation:

Start with the 4000 that's in the account. Then subtract 3(1050) which represents 3×1050, the cost of three phones.

4000 - 3(1050)

= 4000 - 3150

= 850

He has 850 left in his account.
