Answer:
14 five-dollar bills
Explanation:
Let
x-----> the number of five-dollar bills
y----> the number of twenty-dollar bills
we know that
x+y=32 ----> y=32-x ----> equation A
5x+20y=430 ----> equation B
Substitute equation A in equation B and solve for x
5x+20(32-x)=430
5x+640-20x=430
20x-5x=640-430
15x=210
x=14 five-dollar bills
Find the value of y
y=32-x ----> y=32-14=18 twenty-dollar bills
