Q: Emily want to purchase a computer that sells for $1250. She can either pay the total amount at the time of purchase, or she can agree to pay the store $115 down and $85 a month for 15 months. How much money can she save by paying the total amount at the time of purchase?


A:


If she pays $115 down, then $115 is subtracted from $1250 to get 1250-115=1135. So she still needs to pay off $1135. Now if she pays $85 a month for 15, then she is paying a total of 85%2A15=1275 (just multiply the amount by the time). So at the end of 15 months, she has paid $1275 (ignoring the down payment).

Now just take the difference of the amount that she owes (1135) from the amount she will pay if she finances (1275) to get

1275-1135=140

So if she decides to finance, she will be paying an extra $140. So she can save $140 if she pays the total amount at the time of purchase.
