Susan had a total of 204 red and green pens. She gave away 1/4 of the red pens and 1/2 of the green pens. She gave away 64 pens in total.

Question

Question: How many green pens did she give away?

 

Too less information for me to solve...

Answer 1

Muhammad got the right values of r and g.  However the question asks how many green pens she gave away.

 

0.5g  represents the number of green pens she gave away. Multiply 0.5 by the value of g that was just found.  g=52

 

 

0.5 × 52 = 26

 

Susan gave away 26 green pens.

 

 

Answer 2

This is a system of equations.

r = red pens

g = green pens

 

r+g = 204

.25r + .5g = 64

 

multiply the second equation by 2.....

 

r+g = 204

.5r + g = 128

 

Subtract the second equation from the first......

 

.5r = 76

 

r = 152 red pens

g = 52 green pens
