Linda, Aldo, and bob have a total of 70 in their wallets. Bob has 3 times what Linda has. Linda has 5 more than Aldo. How much do they have in their wallets?
L, A, B = the amount of money each person has. L + A + B = 70 B = 3L L = A +5 or A = L-5 Set up an equation in L only: L + L - 5 +3L =70 5L -5 = 70 5L =75 L = 15 follows B=3*15 =45 A = 15 - 5 = 10
