Answer:
0.25 * 100 = X
Step-by-step explanation:
If there is a winning ticket in 1 out of every 4 boxes of French Fries sold, then that means there is a 25% chance of getting a winning ticket ( 1 / 4 = 0.25 ) . Therefore we can calculate the total amounts of winning coupons per day with the following formula.
0.25 * S = X
Where S is the amount of boxes sold and X is the amount of winning coupons. If the location sells 100 boxes then...
0.25 * 100 = X
25 = X
We can see that the amount of winning coupons in 100 boxes sold will be 25.
