Question

A bag contains green marbles and red marbles, 36 in total. The number of green marbles is 1 more than 4 times the number of red marbles. How many green marbles are there?

Answer 1

29

Explanation:

Total marble = 36

Let red marbles be X

Then green marble is 4X + 1

And 4X + 1 + X = 36

5X = 36 - 1

5X = 35

X = 35/5 = 7

So, green marbles = 4X + 1

= 4(7) + 1

= 29
