Question 1098948: An apple contains 140 calories and 2 g of fiber. A banana contains 95 calories and 5 g of fiber. Set up a system of equations that could be solved to determine the number of apples (AA) and bananas (BB) that should be eaten to obtain 3620 calories and 110 g of fiber.

You can put this solution on YOUR website!
.
140*A + 95*B = 3620,     (1)    (counting calories)
  2*A +  5*B =  110.     (2)     (counting fiber)


The setup is done.

And since the post does not ask to solve it, I leave it without the solution.
