Answer: If Frank and John can meet these goals with their diets , they will weigh same after 9.6 weeks and they will weigh 179.2 pounds.
Step-by-step explanation:
Let x = Number of weeks.
As per given question ,
Weight of Frank after x weeks = 160+2x (pounds)
Weight of John after x weeks = 208-3x (pounds)
When Weight of Frank= Weight of John
![\Rightarrow\ 160+2x= 208-3x](https://tex.z-dn.net/?f=%5CRightarrow%5C%20160%2B2x%3D%20208-3x)
![\Rightarrow\ 2x+3x= 208-160](https://tex.z-dn.net/?f=%5CRightarrow%5C%202x%2B3x%3D%20208-160)
![\Rightarrow\ 5x= 48\Rightarrow\ x=\dfrac{48}{5}=9.6](https://tex.z-dn.net/?f=%5CRightarrow%5C%205x%3D%2048%5CRightarrow%5C%20x%3D%5Cdfrac%7B48%7D%7B5%7D%3D9.6)
Weight of Frank after 9.6 weeks = 160+2(9.6) = 179.2 pounds
Weight of John after 9.6 weeks = 208-3(9.6)=179.2 pounds
Hence, If Frank and John can meet these goals with their diets , they will weigh same after 9.6 weeks and they will weigh 179.2 pounds.
