CRQ #13: Don works in home construction. He determined that the
function t(A)=144A/9.252 gives the total number of 9 in. tiles needed to cover
an area of A square feet, when spacing the tiles a quarter inch apart.
Find t(400) and explain what it means.
Please help me

Answer 1

`t(400)=673`.

It means that 673 of 9 inch tiles are required to cover an area of 400 square feet, when spacing the tiles a quarter inch apart.

Explanation:

Given:

The function relating number of 9 inch tiles required and area to cover is:

`t(A)=(144)/(9.25^2)A`

Now, plug in 400 for
`A` to evaluate
`t(400)`.

`t(400)=(144)/(9.25^2)* 400=(144* 400)/(85.5625)=(57600)/(85.5625)=673.19\approx6225`

Therefore, Don required 673 of 9 inch tiles to cover an area of 400 square feet, when spacing the tiles a quarter inch apart.
