Answer 1

Donna will have to pay $67.985125 at the register, including the 7% sales tax.

Explanation:

Donna bought 3 pairs of pants for $28.50 each.

So, the cost for 3 pair of pants
`=(28.50* 3)dollars= 85.50` dollars.

She also bought a necklace for $12.25

Thus, the cost for her entire purchase will be:
`(85.50+12.25) dollars = 97.75` dollars.

She received a discount of 35% off her entire purchase. So, the amount of discount
`=(97.75* 0.35)= 34.2125` dollars.

Thus, the total selling price will be:
`(97.75-34.2125)= 63.5375` dollars.

Percentage of sales tax is 7%. So, the amount of sales tax
`=(63.5375* 0.07)= 4.447625` dollars.

Thus, the total amount Donna have to pay at the register
`=(63.5375+4.447625)=67.985125` dollars.
