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 ea

Vladimir [108]

Cost of 1CD=$9.99

$\\ \sf\longmapsto 6(9.99)$

$\\ \sf\longmapsto 59.94$

Now discount is 25%

Discount:-

$\\ \sf\longmapsto 59.94\times 25\%$

$\\ \sf\longmapsto 59.94(0.25)$

$\\ \sf\longmapsto 14.985$

Approximately $15.00
