Answer:
15 ans rln 1 and 17 ans rln3
Answer:
There are 132 red marbles and 12 black marbles
Work:
I made a ratio of 11:1 and multiplied both sides by 12 which gave me 132:12
132+12=144
Set an equation:
Let x=the total amount of extra money
120+30•12+x=900
120+360+x=900
480+x=900 Subtract 480 from both sides.
x=420
Now divide by 12 to find the amount for each month
