A company manufactures shaving sets for $5 each and sells them for $7 each. How many shaving sets must be sold for the company to recover an initial investment of $45,000 and earn an additional $15,000 as profit.

30,000 shaving sets must be sold.

Step-by-step explanation:

With each shaving set the company makes a profit of $2. Added together the company needs to make $60,000, to cover the initial investment and profit. By dividing the amount of money that needs to be made (60,000) by the amount of profit that each set earns (2), we get the amount of 30,000 products that need to be sold.
