Question

Karen needs to find a courier to deliver a package the first courier charges a fee of $20 plus $2 per pound the second charges $12 plus $3 per pound karen determines that given her packages weight the two courier services are equivalent in terms of cost. how much will it cost? what is the weight?

Answer 1

Explanation:

Let's call the weight of Karen's package "w" in pounds.

For the first courier, the cost is given by:

Cost = 20 + 2w

For the second courier, the cost is given by:

Cost = 12 + 3w

We know that these costs are equivalent, so we can set them equal to each other:

20 + 2w = 12 + 3w

Simplifying this equation, we get:

8 = w

So the weight of Karen's package is 8 pounds.

To find the cost, we can plug this weight into either of the equations above:

For the first courier:

Cost = 20 + 2(8) = 36

For the second courier:

Cost = 12 + 3(8) = 36

So it will cost Karen $36 to deliver her package, and the weight of the package is 8 pounds.
