There are 2100 cups in the package.
Step-by-step explanation:
Given,
Number of green cups in package = 630
This represent 30% of the total package.
Let,
x represent the total number of cups in package.
30% of x = 630
[tex]\frac{30}{100}*x=630\\0.30x=630[/tex]
Dividing both sides by 0.30
[tex]\frac{0.30x}{0.30}=\frac{630}{0.30}\\x=2100[/tex]
There are 2100 cups in the package.
