Answer:
Total number of cups in package are 2400.
Explanation:
Given : An economy package of cups has 720 green cups.
And the green cups are 30% of the total package.
We have to find the number of total cups in the package.
Let the package contain x cups in total.
Given: green cups are 30% of the total package that is 30% of x,
Also , given package has 720 green cups.
Thus, 30% of x = 720
![30\%* x= 720](https://img.qammunity.org/2020/formulas/mathematics/high-school/755urx0tk0rp4cq4ih6b5b3b6e54xhauit.png)
Solving for x, we have,
![(30)/(100)* x=720\\\\\ x=720 * (100)/(30)\\\\\ x=2400](https://img.qammunity.org/2020/formulas/mathematics/high-school/hqrogx4b28je36uq21nkhp9ys0yxu1qfq5.png)
Thus, total number of cups in package are 2400.
