An economy package of cups has 720 green cups. If the green cups are 30% of the total package, how many cups are in the package?
TEA [102]

Answer:

Total number of cups in package are 2400.

Step-by-step 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\%\times x= 720

Solving for x, we have,

\frac{30}{100}\times x=720\\\\\ x=720 \times \frac{100}{30}\\\\\ x=2400

Thus, total number of cups in package are 2400.
