Hosting a dinner party for 38 people, you plan to serve peach pie for dessert. Each pie has 8 slices. How many pies must you buy to ensure each guest gets 1 slice?

Answer 1

5 pies

We know that 1 pie has 8 slices and there are 38 people. That means if each guest is to have 1 slice, there needs to be 38 slices

Hence, to know how many pies we need to buy, we divide 38 by 8 ie #38/8=4.75#

However, there is no such thing as #4.75# of pies so we round it up to 5 pies in total.

To ensure each guest gets 1 slice of peach pie, you would need to buy 5 pies. (38 guests * 1 slice per guest) / 8 slices per pie = 4.75 pies. Since you cannot buy a fraction of a pie, you would need to round up to the nearest whole number, which is 5. Therefore, you would need to buy 5 pies to ensure each guest gets 1 slice.
