x-6 = 5(x + 2) equation/Question
step 2
x-6 = 5(x + 2) simplify
x+(-)6=5x+10
x-6=5x+10
step 3
x-6=5x+10 subtract 5x
-4x-6=10

A 15% percent markup means that the typewriter cost was increased by 15%, or 0.15 by moving the decimal 2 places to the left. If the original price was x, and 15% of it is 0.15*x, we can add them up to get 1.15*x=129.95. Dividing both sides by 1.15, we get x=113 dollars
