X : red marble
Y: blue marble
X+Y= 81 (•)
Y= 5X+3 (••)
>>> 6X+3= 81 >>>> x=13 and y = 68
X=10 and y=5 so it's the first option

Step-by-step explanation:
To do this problem, we need one more piece of information. He need to know the percent of the quarters that are from New York.
If you had that number, just multiply it by 300.
For example, if 10% of the coins were from New York, just multiply by 0.1.
0.1 x 300 = 30
I hope this helps you
(f-g)(x)=2x+1-(x^2-7)
(f-g)(x)=2x+1-x^2+7
(f-g)(x)= -x^2+2x+8
