Answer:
$10.80
Step-by-step explanation:
1. Multiply $12 X 10%
2. convert 10% to decimal = .10
3. 12 X .10 = 1.20
4. Subtract 1.20 from 12
5. 12-1.20 = 10.80
A) x * 7 = y
B) y + 7 +1 = 9x
A) x = y / 7
Substituting this into B)
B) y + 8 = 9(y/7)
Multiplying both sides by 7
B) 7y + 56 = 9y
2 y = 56
y = 28
x = 4
***************************************************
Double Check
4 * 7 = 28 + 7 = 35
9*x = 36
