Question

An online grocery store charges $0.10 per pound of produce for handling and delivery after

an annual membership cost of 75 dollars. If a customer does not pay for the membership, the
cost per pound of produce is $0.25.
How many pounds of produce do you have to buy for the membership to be worth it?

Answer 1

They must buy 501 pounds of produce for the membership to be worth it.

Explanation:

You can solve this question by first finding the difference between $0.10 and $0.25.

With some simple subtraction (0.25-0.10) we can find that the difference is that a non-membership person would pay $0.15 per pound.

You then divide 75 by 0.15 to find the extra weight it would take for the produce to equal $75. You should get 500 pounds.

At 500 pounds, the price would be equal if you had a membership or not.

You then must add 1 pound to make it more favorable to have the membership.

At 501 pounds the person with the membership would pay $125.10 and the person without the membership would pay $125.25
