Question

A bag contains blue marbles and red marbles, 107 in total. The number of blue marbles is 7 more than 4 times the number of red marbles. How many blue marbles are there?

Answer 1

Answer: red is 13.36

Blue is 93.625

Explanation:

Let the red marbles be y

Based on the question,red is 4times which means 4y

And blue is 7times greater than red which means 7(4y)

Blue + red=107

7(4y) + 4y=107

28y+4y=107

32y=107

Divide both sides by 32

Y=3.34

Red =4y

Red= 4(3.34)

Red =13.36

Blue= 7(4y)

Blue=7(4×3.34)

Blue= 93.625
