Question

Jessica bought a new computer for $800. She put $120 down and got a student discount of $50. Her mother gave her 1/2 of the balance for her birthday. Use the numerical expression to find the amount that Jessica still owes for the computer. {800 - (120 + 50)} divided by 2

Answer 1

120 + 50 = 170
170-800= 630
630/2=315

Answer 2

Jessica still owes $315 because the discount brought her $800 price down to $750 then she put down $120 which made it $630 in total and then her mother gave her half of the balance so that would be $315 and then all that Jessica has to pay is 315 more dollars 2 equal the total of $750
