Answer:

  Store A has a better deal because $402.90 is less than $404.10.

Step-by-step explanation:

<u>Store A</u>

The $25 off coupon reduces the price to ...

  $499 - 25 = $474

The discount from this amount is 15%, so is ...

  $474 × 0.15 = $71.10

The final amount paid is then ...

  $474.00 -71.10 = $402.90

(<em>Side note</em>: you can select the correct answer at this point, because only one answer shows this value.)

___

<u>Store B</u>

After the $20 off coupon, the price is ...

  $469 -20 = $449

The additional 10% discount amounts to ...

  $449 × 0.10 = $44.90

So, the final price is ...

  $449.00 -44.90 = $404.10

___

Now, you know that Store A offers the better price because $402.90 is less than $404.10.

I understand the simple interest part, however I don’t understand the compounded interest part, need help quick.
Burka [1]
Compound interest is the starting amount x (1+ the interest rate as a decimal)^ the time in years=the final amount.

In your case, the equation will be $1000*(1+0.10)^how many years= the final amount.
