Problema Solution
A truck is loaded with two different types of boxes. If 150 of box A and 115 of box B are loaded onto the truck, its capacity of 10 tonnes is reached. If 300 of box A are loaded, the truck can only take 30 of box B before the capacity of 10 tonnes is reached. Find the weight of each box
Answer provided by our tutors
let 'x' represent the weight of box A and 'y' the weight of box B
10 tonnes = 10*2000 = 20000 pounds
150A + 115B = 20000
300A + 30B = 20000
solving this system we have:
A = 56 2/3
B = 100
box A weighs 56 2/3 pounds, box B weighs 100 pounds
