Answer 1

Answer: B

Step-by-step explanation: A sweater was marked up from $40 to $50. If p is the percent increase in the price of the sweater, which proportion can be used to calculate p?

$40 - $50 - = P

$50 100

Answer 2

10/40 = p/100

The price increased by $10, so that over the total is the percent you are looking for. Set it equal to the percent over the total, which is 100 for all percents.
