Question

Janet's Junk Shop is having its annual sale. Matt wants to buy a mixer that originally sold for $28.62 and is now on sale for off. Matt also has a coupon for an additional 15% off the discounted price.

How much will Matt pay for the mixer?

Answer 1

`n\% \:\:off = (100 -n)\% \:\: of \:the\: original \:price`

`FinalPrice =`

`(Original Price *((100\% - Discount)/(100\%)))*((100\% - Discount_2)/(100\%)) =`

`\big(\$28.62*((100\% - 25\%)/(100\%))\big) *((100\% - 15\%)/(100\%)) =`

`\big(\$28.62*((3)/(4))\big) *((17)/(20)) \approx \$18.25`

Matt will pay
`\$18.25` for the mixer
