Question

A yo-yo factory has fixed operating costs of $5000 per day plus costs of $2 per yo-yo produced. If a yo-yo sells for $5.50, what is the minimum number that must be sold in a day to earn a profit?

Answer 1

1429

Explanation:

Break even is expressed as:

5000+2x = 5.5x

5000=5.5x-2x

5000=3.5x

`(5000)/(3.5) = (3.5x)/(3.5)`

1428.57=x

Since you cannot sell a fractional yo-yo, round up to 1429
