Solution:

Given, A student has $1 bills and $5 bills in his wallet.  

He had a total of 15 bills that are worth $47.  

We have to find how many of each type does he have?

Let the number of $1 bills be n then number of $5 bills be 15 – n.

And, according to given information, $1 x n + $5 x (15 – n) = $47

n + 5 x 15 – 5n = 47

n – 5n = 47 – 75

-4n = -28

4n = 28

n = 7

Then, number of $5 bills = 15 – 7 = 8.

Hence, the number of $1 bills are 7 and $5 bills are 8.
