Question

A Cell phone company found that 20 of their 150 phones were defective in May. If they produced 750 phones in June, how many would expect to be defective.

(P.S Show work)

Answer 1

150/20=7.5 rounded it 8 so for ever 8 phone 1 defective


750/8=93.75 rounded up = 94 phones

your answer is 94 phones

Answer 2

100

Explanation:

We can determine the percent of defective phones to non-defective phones by dividing the defective phones by the total phones:

`=20/150=0.1333`

Therefore 13.33% off the phones will be defective. We can calculated the amount of phones out of 750 that will be defective:

`=0.1333\cdot{750}=99.99=100`

100 of the 750 phones could be defective
