Question

A bag contains purple marbles and white marbles, 104 in total. The number of purple marbles is 2 more than 5 times the number of white marbles. How many purple marbles are there?

Answer 1

Let white marbles = x

Purple marbles = 5x + 2

Given:

x + 5x + 2 = 104

6x = 102

x = 17

Purple marbles = 5(17) + 2 = 85 + 2 = 87
