Question

A thrift store was selling an Atari 2600 for $80 before deciding to have a 40% off promotion. A customer comes in to buy the console and pays with a 10% off any one item coupon. The coupon states that the 10% off coupon applies after any in-store promotions. The customer expects to get 50% off overall and pay 40.00. Is the customer correct?

Answer 1

The customer is incorrect. They will pay $43.20 not $40.

Explanation:

Since a thrift store is having 40% of $80, we have to calculate that. Doing so, we have to create proportions:

(The "/" sign is fraction)

1. x/80=40/100 2. 40*80=3200 3. x*100=100x 4. 100x=3200

5. x=3200/100 6. x=$32

Since $32 is 40% of $80, we have to do $80-$32=$48

So the thrift shop is lowering the price to $48.

But we can't forget about the 10% off coupon from the customer.

Now we have to find out what is 10% of $48. $48/10= $4.8

That's not our answer though. The final step is to do $48-$4.8 which gets our answer of $43.20 .
