Answer:

122 one dollar bills

11 five dollar bills

5 ten dollar bills

Step-by-step explanation:

t = ten dollar bills

f = five dollar bills

w = one dollar bills

227 = 10t +5f +1w

t+6 = f

w = 25t-3

We can get the first equation in terms of t

227 = 10t+5(t+6) +1(25t-3)

Distribute

227 = 10t +5t +30 +25t -3

Combine like terms

227 = 40t +27

Subtract 27 from each side

200 = 40t

Divide by 40

5 = t

Now find f

f =t+6

f = 5+6 = 11

And find w

w = 25t-3 = 25(5) -3 = 125-3 = 122
