Question

the average number of red, blue, and green beanbags in a store is 136.
there are 30 more red beanbags than blue beanbags. there are 15 fewer green beanbags then blue beanbags. how many green beanbags are in the store

Answer 1

fewer green beanbags of what blue or red

Answer 2

fewer green than blue? sorry edited the question.

Answer 3

Let r = number red beanbags
b = number blue beanbags
g = number green beanbags
From the total number you know that
r + b + g = 136
from "there are 30 more red beanbags than blue beanbags" you know
r = b + 30
and from "there are 15 fewer green beanbags then blue beanbags." you know
g = b - 15
Now substitute what r and g are equal to in the last two equyations into the first equation and solve for b. Then substitute the value of b into the 2nd and 3rd equations to get r and g.

Answer 4

still having trouble with problem blue equals what?

Answer 5

r + b + g =136
make both substitutions for r and g and you get
b + 30 + b + b - 15 = 136
3b + 15 = 336
3b = 321
b = 107
