Cost of repair = $50;
Cost of new bicycle – Credit for old bicycle = 107 – 22 = $85

Excess amount paid to get bicycle = 85 – 50 = 35

The cost to her of purchasing the new bicycle is (35/50)*100% = 70% greater than the cost of having her current bicycle repaired.

The correct answer: C

Hope this helps!

The cost of the new bicycle is 85 dollars after she trades in her current bicycle. So we need to determine 85 is what percent greater than 50:

(85 - 50)/50 * 100 = 35/50 * 100 = 70 percent

Answer: C
