Answer:
So the answer is
Step-by-step explanation:
x)2943
$10.71
Explanation
Step 1
you can easily solve this by using a rule of three.
Let
x represents the money Eileen will pay if her bag weighs 63 pounds
the proportion is the same
then
![\frac{7.14}{42}=\frac{x}{63}](https://tex.z-dn.net/?f=%5Cfrac%7B7.14%7D%7B42%7D%3D%5Cfrac%7Bx%7D%7B63%7D)
Step 2
solve for x
![\begin{gathered} \frac{7.14}{42}=\frac{x}{63} \\ 63\cdot7.14=42x \\ x=\frac{63\cdot7.14}{42} \\ x=\frac{449.82}{42} \\ x=10.71 \\ \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Cfrac%7B7.14%7D%7B42%7D%3D%5Cfrac%7Bx%7D%7B63%7D%20%5C%5C%2063%5Ccdot7.14%3D42x%20%5C%5C%20x%3D%5Cfrac%7B63%5Ccdot7.14%7D%7B42%7D%20%5C%5C%20x%3D%5Cfrac%7B449.82%7D%7B42%7D%20%5C%5C%20x%3D10.71%20%5C%5C%20%20%5Cend%7Bgathered%7D)
