b. Your cost is $50

Answer 1

a. $312.5

b. $62.5

Explanation:

[a] To increase the price by 125%, we will multiply our cost by 125%. A percent divided by 100 becomes a decimal, and then we multiply.

$250 * 125% = $250 * 1.25 = $312.5

[b] We will follow the same step, but with a different starting amount. To increase the price by 125%, we will multiply our cost by 125%. A percent divided by 100 becomes a decimal, and then we multiply.

$50 * 125% = $50 * 1.25 = $62.5
