The net on the left is correct.
surface area is the sum of all side areas.

15*5 = 75
5*12 = 60
15*12 = 180
15*13 = 195

75 + 60 + 180 + 195 = 510

charle [14.2K]

Alice has read 150 pages, you would multiple 200 by .75 (75%). If Nina had read 50% of her book and she read 150, you multiple by 2, and get 300. So Nina has 300 pages in her book.

oee [108]

Answer:

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

Step-by-step explanation:

Donna bought 3 pairs of pants for $28.50 each.

So, the cost for 3 pair of pants $=(28.50\times 3)dollars= 85.50$ 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 $=(97.75\times 0.35)= 34.2125$ 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 $=(63.5375\times 0.07)= 4.447625$ dollars.

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