Multiply -7 to both sides:
Add 10 to both sides:
Divide 2 to both sides:
<em>It would be $46 because when you add the 15% tax to it, the total is $61. </em>
<em>$61-15%=$46. To check $46+15%=61! Hope i helped! :-)</em>
4.5(4-x) + 36 = 202 - 2.5(3x + 28)
Distributive property
18 - 4.5x + 36 = 202 - 7.5x - 70
Combine like terms
-4.5x + 54 = -7.5x + 132
Add 7.5x to both sides
3x = 78
Divide both sides by 3
x = 26
Speed=distance/time
speed=37.5/3
=12.5 m/s
8% of x = $18.80
x = 18.80/8%
x = 18.80/0.08
x = $235
