Answer:
x=4
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3(x+2)=2(x+5)
(3)(x)+(3)(2)=(2)(x)+(2)(5)(Distribute)
3x+6=2x+10
Step 2: Subtract 2x from both sides.
3x+6−2x=2x+10−2x
x+6=10
Step 3: Subtract 6 from both sides.
x+6−6=10−6
x=4
1. Percent error is

2. The cost will be $31.95*(1+0.075) = $34.35
The 1 represents 100% of the original amount of $31.95, and now we add 7.5% (0.075) to the 100%. In other words we multiply $31.95 by 107.5%.
