Question

A package delivery firm charges according to the

package's weight.

The charge is $1.10 for packages
weighing up to three ounces, inclusive.

For packages
weighing more than 3 ounces and up to ten ounces,
inclusive, the charge is $2.25.

For packages weighing
more than ten ounces and up to fifteen ounces, inclusive,
the charge is $3.35.

For packages weighing more than fifteen ounces, the company has a different price setting.


Let C(x) be the cost in dollars according to the package's
weight (x). write a piecewise-defined function that
represents the situation.

Answer 1

see the explanation

Explanation:

Let

x ----> the package's weight

C(x) -----> the charge in dollars

we know that

1) For

`0\ oz < x \leq 3\ oz`

`C(x)=\$1.10`

2) For

`3\ oz < x \leq 10\ oz`

`C(x)=\$2.25`

3) For

`10\ oz < x \leq 15\ oz`

`C(x)=\$3.35`

2) For

`x > 15\ oz`

`C(x)` -----> the company has a different price setting
