Answer:
10 one-dollar and 4 five-dollar bills.
Step-by-step explanation:
Let x = the number of one-dollar bills and y = number of five-dollar bills.
Then:
x + y = 14
x + 5y = 30 (using the values of the bills)
Subtracting the 2 equations:-
-4y = -16
y = 4
so x + 4 = 14
x = 10.
There are 10 one-dollar bills and 4 five-dollar bills.
