ANSWER: 9/91
EXPLANATION:
4x+2/39=5x-1/21
-x+2/39=-1/21
-x=-9/91
x=9/91
Step-by-step explanation:
Ratio 9:2, therefore total number of shares is 11.
because 9+2 = 11
total cards = 8,250
8,250/11 = 750
This is the value for one of the shares.
As the ratio is 9:2 we can find:
9 X 750 : 2 X 750
To see what everyone has won.
T-shirts : 2 X 750 = 1,500.
