Aschool purchases jars of marbles. * each jar contains 500 pieces of marbles. * each jar costs $10. how much does the school have to charge for each piece of marbles to make a profit of $25 per jar? a. $0.07 b. $0.10 c. $0.14 d. $0.25

a. $0.07

Step-by-step explanation:

Profit = Charge -Cost

We want to make a profit of 25 and the cost is 10

25 = Charge -10

Add 10 to each side

25+10 = Charge -10+10

35 = Charge

We need to charge 35 per jar.

Each jar contains 500 marbles

The cost per marble is Cost/ number of marbles

cost per marbles = $35 / 500

                             = $.07

is means division by fractions
