Step-by-step explanation:
I think that the right question is:
In the system of equations shown, x represents the number of pounds of strawberries, and y represents the number of pounds of grapes in a fruit mix. x y = 15.82 and x - 1.90y = 72.5. what is the difference between the number of pounds of strawberries and the number of pounds of grapes in the mix
Given that:
x represents the number of pounds of strawberries, and y represents the number of pounds of grapes in a fruit mix.
The equation relating x and y is given by the equation:
Subtracting equation 2 from equation 1, we get:
Putting y = 19.54 in equation 1 to get:
Therefore, the difference between the number of pounds of strawberries and the number of pounds of grapes in the mix is given by:
The difference between the number of pounds of strawberries and the number of pounds of grapes in the mix is 33.42 pounds.
