Answer:
=22.47
Step-by-step explanation:
We are buying 2 shirts
Before discount 2*15 = 30
We get 30% off. That means we pay 70 percent of the price
$30 * 70% =
30 *.7
21
The cost of the shirts before tax is 21 dollars
Tax is the cost of the shirts after discount times the tax rate
tax = 21 * 7%
tax = 21 *.07
tax =1.47
We add the tax to the cost of the shirts
Final cost = discount price + tax
=21+1.47
=22.47
The total cost of 2 shirts on sale, including the 7% sales tax, is $22.47.
The subject of this question is Mathematics, specifically a problem of applying percentage for discounts and tax. To calculate the sale price of a single shirt, you need to take 30% off the original price. Calculate 30% of $15, which is $4.50. Subtract this from the original price, which leaves you with $10.50 as the sale price of one shirt. However, you want to buy 2 shirts, so the cost before tax is $21. Next, you need to calculate the sales tax. Multiply $21 by 7%, which is $1.47. Add the $1.47 sales tax to the $21 cost before tax, and you get the final total cost: $22.47.

and a height of 17.25 feet. Jamal's
neighbor's roof has an area of 942 square
feet. What is the difference in area
between Jamal's roof and his neighbor's?
Answer: 103.65 square feet
Step-by-step explanation:
To find Jamal’s roof area: 97.2 x 17.25 = 1,676.7. Divide by two because it’s a triangle (gets you to 838.35).
Subtract 838.35 from neighbors roof area (gives you 103.65)

Answer:
Step-by-step explanation:
If she sells 8 dozen, she will get exactly 120 dollars. But that is not what the question says.
Sales = 8 * 15 = 120
The question says that she wants to make more than 120 dollars. Therefore the circle must be an open one. B is the proper answer. A is close but A means that she is willing to stop her sales when they reach 120 dollars. Not so.
A is not the answer.
