2.5 * 3 = ?

7.5

Right.

10

7 1/2

To find out how many bottles of cranberry juice Cindy will need to serve 100 guests, we need to determine how many bottles of cranberry juice are needed per guest and then multiply that by the number of guests.

In this case, we know that 3 bottles of cranberry juice are needed to serve 40 guests. So, to find out how many bottles are needed per guest, we can divide the number of bottles by the number of guests:

3 bottles / 40 guests = 0.075 bottles per guest

Now, we can multiply the number of bottles per guest by the number of guests to get the total number of bottles needed for 100 guests:

0.075 bottles per guest * 100 guests = 7.5 bottles

Therefore, Cindy will need 7.5 bottles of cranberry juice in order to make enough punch to serve 100 guests. Since we can't have half a bottle, she would need to round up to 8 bottles to ensure there is enough punch for everyone.
