The cost of a bicycle wheel was $62 last week. This week, the cost rose to $79 . Find the percentage increase. Round your answer to the nearest tenth of a percent.

Answer 1

Difference of $62 and $79 is 24.1%

62 - 79/((62 + 79)/2) = 17/70.5 =

0.24113475177305 x 100 = 24.113475177305%

Answer 2

the percentage increase is 27.4%

Explanation:

To find the percentage increase, we can use the formula:

(New cost - Old cost) / Old cost x 100% = Percentage increase

(79 - 62) / 62 x 100% = 27.41%

The percentage increase is 27.41%. Rounded to the nearest tenth of a percent, the percentage increase is 27.4%
