Answer:
Step-by-step explanation:
1. Subtract 10 from both sides. Then:
2. Divide both sides by -2. Notice that the direction of the symbol of the inequality will change. Then:
3. Add 22 to both sides. Then:
4. Divide both sides by -7. Notice that the direction of the symbol of the inequality will change. Then:
5. Subtract 30 from both sides. Then:
6. Divide both sides by -5. Notice that the direction of the symbol of the inequality will change. Then:
7. Subtract 13 from both sides. Then:
8. Add 12 to both sides. Then:
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.
