Question

Because of damage, a computer company had 5 tablets returned out of the 80 that were sold. Suppose the number of damaged tablets sold continue at this rate. How many tablets should the company expect to have returned if it sells 400 of them?

Answer 1

we are told that there 5 damaged tablets out of 80 that are sold. Therefore, the rate of damaged tablets per sold tablets is:

`\frac{5\text{ damaged}}{80\text{ sold}}`

Multiplying this rate by the 400 sold tablets we get:

`\frac{5\text{ damaged}}{80\text{ sold}}*40\text{0 sold}`

Solving we get:

`\frac{5\text{ damaged}}{80\text{ sold}}*40\text{0 sold}=25\text{ damaged}`

Therefore, if the rate continues, the company can expect to return 25 tablets.
