200
Let the total number of customers that day be "x"
30% of total customers bought a snack and that is 120.
So we can say:
30% of total (x) is 120
Note: 30% converted to decimal is 30/100 = 0.3
This can be translated to an algebraic equation as:
0.3x = 120
Now, we can solve for x, the total customers:
0.3x = 120
x = 120/0.3
x = 400
Since, 80% bought drink, we find 80% of 400:
80% = 80/100 = 0.8
0.8 * 400 = 320
The store sold 320 drinks and 120 snacks. So drinks outweigh snacks be:
320 - 120 = 200
So,
200 more drinks than snacks
