If wholesale cost is x, then retail is x plus the percentage change in x. (1 + .34)x = 1.34x.
<span>To calculate the percentage increase: First: work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100.
1520-950=570
570÷950= 0.6 × 100=60%
