Question

At a local market the cost of apples is directly proportional to the weight of the apples. Brian bought 10 pounds of apples for the cost of $15.00

Answer 1

To find this proportion, you need to make a fraction. Basically you want to find money per pound. So set up your fraction like that. $15.00/10 pounds. That means it costs $1.50 for every 1 pound.
