1) Cost of repairing = 12.5 ( for one year ), Therefore for 2 years it would be  $ 25 .

2) Cost of new pair which will last for 2 years is  $ 28 .

Percentage change formula =   ( Final value - Initial value ) / ( Initial Value ) * 100  . In this case the final value would be the price of new shoe & initial value would be the cost of repairing the old shoe.

I.e ( 28 - 25 ) / ( 25 ) * 100 = 12 %.

Ans is C.

Given: 
1. A certain pair of used shoes can be repaired for $12.50 and will last for 1 year. 
2. A pair of the same kind of shoes can be purchased new for $28.00 and will last for 2 years.

Asked: The average cost per year of the new shoes is what percent greater than the cost of repairing the used shoes?

Average cost per year of the new shoes = 28/2 = $14
Average cost per year of the repaired shoes = $12.5

The average cost per year of the new shoes is what percent greater than the cost of repairing the used shoes = 14/12.5 -1 = 1.5/12.5 = (150/12.5) % = 12%

IMO C

QuantMadeEasy · Answer

Cost of repairing for 2 years is 25$
Cost for new shoes is 28$
Cost of new shoes is greater than cost of repairing = 3/25 *100% = 12%

C is correct

ScottTargetTestPrep · Answer

The average cost per year of the new shoes is 28/2 = $14, so it’s:

(14 - 12.5) / 12.5 = 1.5/12.5 = 12/100 = 12% greater than the cost of repairing the used shoes.
