Answer:
3. $1.86
4. $1.38
Explanation:
3. Each CD costs $10.98, and with 5.25% sales tax, the total cost of each CD is:
$10.98 + ($10.98 x 0.0525) = $11.57
To find the maximum number of CDs that can be purchased without exceeding the gift card balance, divide the gift card balance by the cost per CD:
$25.00 ÷ $11.57 ≈ 2.16
Since you cannot buy a fraction of a CD, you can buy a maximum of 2 CDs. The total cost of the CDs will be:
2 x $11.57 = $23.14
Therefore, the balance on the gift card after the purchase will be:
$25.00 - $23.14 = $1.86
4. The cost of 12 individual chip bags at the local store is:
12 x $0.99 = $11.88
The cost of 12 bags bought in bulk at the wholesale club is $10.50. To find the savings per dozen bags, subtract the bulk price from the individual price:
$11.88 - $10.50 = $1.38
Therefore, you save $1.38 per dozen bags by buying in bulk.
