These are the fees for sending a package by media mail:

$\bullet$ $\$2.41$ for the first pound

$\bullet$ $\$0.41$ per additional pound for the next six pounds

$\bullet$ $\$0.39$ per additional pound after that

for example, a two-pound package costs $\$2.82$ to send by media mail.

if a package full of books costs $\$7.99$ to send by media mail, how many pounds does the package weigh? explain your work in complete sentences.

formatting tip: to write a dollar sign, use $\verb#\$#$. if you use just $, the homework system will think that is $\latex$. review your solution for formatting problems.

First pound costs =

Next 6 pound costs = * 6 =

cost per additional pound is after 7 pounds.

Let x be the weight of package in pounds

additional pound is (x-7)

Cost of package = cost of 1 pound + cost of 6 pounds + cost of additional pounds

Given cost of package = 7.99

Cost =

Subtract 4.87 on both sides

Add 2.73 on both sides

Divide by 0.39 on both sides

The package weight 15 pounds
