Question 1166779: 1. From his daily allowance, Dante saved Php 37.50 consisting of 1-peso and 25-centavo coins. If there is an equal number of 1-peso and 25-centavo coins, how many of each kind does he have?
Use the grouping method.
Combine coins in groups, in a way that each group has one 1-peso and one 1-centavo coins.
According to the condition, this grouping does work.
Then each group is worth 100+25 = 125 centavo,
and the number of groups is = 30.
So, you conclude that the collection contains 30 1-peso and 30 25-centavo coins. ANSWER
