Question

A CD store is having a sale. All CDs are 25% off sticker price. Estimate the amount you would save when buying 6 CDs at $9.99 each before discount.

A. $5.00
B. $30.00
C. $10.00
D. $15.00
E. $25.00​

Answer 1

Cost of 1CD=$9.99

Cost of 6CDs

`\\ \sf\longmapsto 6(9.99)`

`\\ \sf\longmapsto 59.94`

Now discount is 25%

Discount:-

`\\ \sf\longmapsto 59.94* 25\%`

`\\ \sf\longmapsto 59.94(0.25)`

`\\ \sf\longmapsto 14.985`

• Approximately $15.00
