Let ( x ) be the number of red marbles to be added. Initially, there are 10 red marbles and 30 green marbles, making a total of 40 marbles. After adding ( x ) red marbles, the total number of marbles will be ( 40 + x ), and the number of red marbles will be ( 10 + x ). To find ( x ), we set up the equation: [ \frac{10 + x}{40 + x} = 0.6 ] Solving this equation gives ( x = 20 ). Therefore, 20 red marbles must be added to have 60% red marbles in the jar.
