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.

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

step-by-step explanation:

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
