Question 1176639: JΓ©rΓ©my passes a backpack, but he wants to buy a bigger one, with a capacity of 45 to 55 L. he hesitates between two models. The capacity of the model A is 2 times greater than that of the backpack it already has. As for the model B, it can hold 15 L more than its walking backpack. If we added 18L to the capacity of the model A and 28 L to the capacity of model B, both models would have exactly the same capacity, which of the two models should jΓ©rΓ©my choose?
