Answer 1

Answer:

Step-by-step explanation:

$100 bill = x

$50 bill = x+47  $20 bill =3x                                                                                                  100x+50(x+47)+20*3x=7810                                                                                                  

100x+50x+2350+60x=7810

210x+2350=7810

210x=7810-2350

210x=5460

/210

x=26

.$100 bill = x =26

$50 bill = x+47=73

$20 bill = 3x=78                                                                                                               please give brainliest
