A cell phone company sold 450 cell phones in three hour
450 is 30% of the number of phones sold that day
30% of number of phones = 450
We need to find the number of phones for 100%
Let x be the number of cell phones sold that day
30% of x is 450
[tex]\frac{30}{100} * x= 450[/tex]
multiply by 100 on both sides
30 * x = 45000
Divide by 30
x = 1500
So 1500 cell phones are sold that day
