Answer:
The number of pounds of apples is 4.5 and the number of pounds of grapes is 2.5
Step-by-step explanation:
Let
x ------> the number of pounds of apples
(x-2) -----> the number of pounds of grapes
we know that
![1.68x+2.48(x-2)=13.76](https://tex.z-dn.net/?f=1.68x%2B2.48%28x-2%29%3D13.76)
Solve for x
![1.68x+2.48x-4.96=13.76](https://tex.z-dn.net/?f=1.68x%2B2.48x-4.96%3D13.76)
![1.68x+2.48x=4.96+13.76](https://tex.z-dn.net/?f=1.68x%2B2.48x%3D4.96%2B13.76)
![4.16x=18.72](https://tex.z-dn.net/?f=4.16x%3D18.72)
![x=4.5\ pounds](https://tex.z-dn.net/?f=x%3D4.5%5C%20pounds)
so
![x-2=4.5-2=2.5\ pounds](https://tex.z-dn.net/?f=x-2%3D4.5-2%3D2.5%5C%20pounds)
therefore
The number of pounds of apples is 4.5 and the number of pounds of grapes is 2.5
