Take a ruler and put it on your desk and mesure from the centimeter side!!

5x - 15 = 50
Add 15 to both sides
5x = 65
Divide both sides by 5
x = 13
Hope this helped :)
Bob's Bikes
260 × 0.2 = 52
260 - 52 = 208
208 × 2 = $416.00
Walt's Wheels
300 × 0.6 = 180
300 - 180 = 120
120 × 2 = $240.00
Carson's Cycles
310 × 0.1 = 31
310 - 31 = 279
279 × 2 = $558.00
(i can't read what it says for $50, comment below if it makes a difference, i'll edit)
Tino's Transportation
260 ÷ 2 = 130
260 + 130 = $390.00
