Answer:
The variables are A and B. A for Andy, and B for Brett. B=18, and A=26
Step-by-step explanation:
A+B=44
A=B+8
B + 8 + B = 44
2B+8=44
2B = 36
B = 18
A = 26
Let's rewrite the information then figure out the answer.
DVD: $9.00 originally but on sale with an 80% discount.
80%=0.80
9.00(0.80) = $7.20
$9.00 - $7.20 = $1.80
Thus, the sales price is: $1.80

The unit rate for the nearest cent per once for each size is 0.24 : 0.19
The number is 175
greater than 100 less than 200, 10-5=5, 5+2=7
