An online buying club offers a membership for $300, for which you will receive a discount of 10 percent on all brand-name items you purchase. How much would you have to buy to cover the cost of the membership?

Answer:$3000

Explanation:

Club membership = $300

Discount = 10% on every items purchased.

How much will be bought?

Assume:

X = how much will be bought

Therefore,

10% of X = $300

10/100*X=$300

0.1*X=$300

0.1X=$300

Divide both sides by 0.1

X=$3,000
