Answer:
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
Answer:
Option A : $0.07
Step-by-step explanation:
Given :
A school purchases jars of marbles.
Each jar contains 500 pieces of marbles.
Each jar costs $10.
To Find : How much does the school have to charge for each piece of marbles to make a profit of $25 per jar?
Solution :
Cost of one jar is $10
Now, school wants to make profit of $25 on each jar .
using formula : Profit = Charge - cost
⇒$25 = charge - $10
⇒$35 = charge
Thus school should charge one jar of marbles of $35.
Since each jar contains 500 marbles.
So,to calculate cost of each marble when charge of jar is $35.
Cost of 500 marbles is $35
Cost of 1 marble = 35/500 = $0.07
cost of each marble when charge of jar is $35 is $0.07
Hence , the school have to charge $0.07 for each piece of marble to make a profit of $25 per jar.
Option A is correct
