Problema Solution
A collection of 45 coins consisting of 5 peso and 10 peso coins has a value of 340 pesos. Find the number of coins of each type.
Answer provided by our tutors
let 'n' represent the number of 5 peso coins, then '45-n' represents the number of 10 peso coins and we have:
340=5n + 10(45-n)
solving for 'n' we have n=22
45-22 = 23
there are 22 5-peso coins and 23 10-peso coins
