Answer:
The plan that will play the computer faster is Plan A $180 down $60/wk payments
Step-by-step explanation:
Hi
Plan A.
As the computer has a value of $840 and Naomi pays $180 initially, she has a balance of $660, so [tex]\frac{\$ 660}{\$60/wk}=11weeks[/tex].
Plan b.
As the computer has a value of $840 and Naomi pays $0 initially, she has a balance of $840, so [tex]\frac{\$ 840}{\$70/wk}=12weeks[/tex].
Hence, Plan B delays 1 week more than Plan A, so if Naomi chooses plan A will pay the computer Faster.
