Formula for Surface Area of a Prism: lateral area + area of 2 ends
Lateral area = 65
Area of base = 16 (2)
SA = 65 + 16(2)
SA = 65 + 32
SA = 97

Step-by-step explanation:
c is the number of cloth gloves sold.
r is the number of cloth gloves sold.
c + r =127
c = 127 - r
6.95c + 8.95r = 1070.65
6.95(127 - r) + 8.95r = 1070.65
882.65 + 2r = 1070.65
r = 94
c = 33
Answer: $18.19.
You'll have to set this up as two separate problems. First, we want to take 15% off the original $20 bill. To do this, you're going to multiply 20 by .15, which gives you $3. So, 15% off $20 is $17.
Now, we want to find 7% of the new bill, so we're going to multiply 17 by .07 to get $1.19, and add it to the $17, making the final bill $18.19. You could also multiply $17 by 1.07 to get your final total without the extra step in the middle, but only do that once you're comfortable with the math.
The answer is D.
15:12 divide both by 3 equals to 5:4
