The cost of a protein bar increased from $2.50 to $2.80. The percent increase to the $2.80 rate was how much?

Detailed Explanation

First subtract the old cost from the new cost: 2.80 – 2.50 = 0.30.

Then divide the difference by the old cost to find the percent difference: 0.30 ÷ 2.50 = 0.12 = 12%.

Then divide the difference by the old cost to find the percent difference: 0.30 ÷ 2.50 = 0.12 = 12%.
