The number of nickels are 8.5 which was calculated by using the given data.
Word problems frequently involve mathematical modelling issues in which data and knowledge about a specific system are provided and a learner is asked to construct a model.
Given: A boy has three more nickels than dimes.
Let, x = number of dimes
Number of nickels = x + 3
He would have spent a quarter of his money if he had spent three nickels and three dimes.
x + 3 + 3x = 25
4x = 25 - 3
x =22/4
x = 5.5
So, number of dimes = 5.5
number of nickels = x + 3 = 5.5 + 3 =8.5
Therefore, the number of nickels are 8.5 which was calculated by using the given data.
