C=p(t+30)
Let’s substitute in our values...
c=2(245+30)
Get the sum of what we have in parentheses...
c=2(275)
And finally
c=550
1. 25% too because it wont change if they have the same amount of marbles.
2. 5% since there is very little gold marbles.
3. Take out 55 red marbles so it could be fair or just take out red marbles in general. That would be fair.
Hope I helped. Have a great day
