Question from Liezel: what is the answer of this problem, If Catherine and Molly has 320 pesos altogether, Molly and Tom have 360 in all . Tom and Catherine have 240 pesos altogether.How much does each of them have? |
Hi Liezel,
Suppose that Catherine has $C$ pesos, Molly has $M$ pesos and Tom has $T$ pesos. Since Catherine and Molly have a total of 320 pesos
\[C + M = 320.\]
What other two equations do you have? Solve the three equations for $C, M$ and $T.$
