3x+5x+21=y 
3x+5x=8x
8x+21=y
     -21  -21
8x=y-21
8x÷8=x
y-21÷8=y-2.625
x= -2.625 + 0.125 y
I think that is right... :)

Part A:

Derrick is incorrect.
A yard is equivalent to 3 feet.
Thus, 20 yards will be equivalent to 60 feet.

The width is 20 yard and 2 feet. It's the same as 60 feet and 2 feet, or 62 feet. Thus, Derrick is incorrect.

Part B:

Let's calculate the area of the parking lot.

We know the width is 62 feet from part A.
The length is 30 yards, or 90 feet.

Multiply the length and width to get the area in square feet.

90 \times 62=5580

The parking lot has an area of 5580 square foot.
It costs 2 dollars per square foot to repave the parking lot. Multiply the area by 2 dollars.

5580 \times 2=11160

It will cost $11,160 to repave the whole parking lot.

Interest=1250-880=370
I=PRT
P=principal
r=rate in deicmal
t=time in years

1 month so t=1/12
P=880
I=370

370=880*r*1/12
370=220/3r
times both sides by 3
1110=220r
