Answer:
A. $0.99p
B. $0.99(8) = $7.92
Step-by-step explanation:
To show that you multiply the unit price by the amount, we can use the variable p. Now, this equation shows that you multiply the price per one pound by the amount of pounds.
If you want to find the cost of 8 pounds, you just put the 8 in place of the p to represent how many pounds. Now, you just need to multiply 0.99 x 8, which equals $7.92.

You would double 16 because 16+16=32
Answer:
see in the picture, the perimeter of this rectangle is
2( x + 3x) = 8x but the perimeter is 65.6
=> 8x = 65.6
<=> x = 65.6/8
=> x = 8.2
Subtract 3 first so it would be 7x=15
then divide by 7 so x would be approximately 2.14
