Question

A clothing store has twice as many blue shirts as red shirts, and one-tenth as many yellow shirts as blue shirts. If the store has twenty red shirts, how many red, blue, and yellow shirts does the store have total?

Answer 1

I got to 60, what do i do with the one-tenth?

Answer 2

64! :D

Answer 3

easiest way of solving is by writing of a system of equations relating everything.
r=# of red shirts
b=# of blue shirts
y=# of yellow shirts

b=2r
y=.1b
r=20

so b = 2r
so b=2*10=20

y=.1*b = .1*20 = 2

total number of shirts = r + b + y = 10 + 2 + 20 = 32

Answer 4

i apologize, my math was terrible there. i just made 20 into 10....

should be b = 2*20 = 40

y = .1 * 40 = 4

total = 64

Answer 5

I don't think it's 32
