Final answer:
To ensure that each guest gets one slice of peach pie, divide the total number of slices needed by the number of slices in each pie and round up to the nearest whole number.
Step-by-step explanation:
To ensure that each guest gets one slice of peach pie, we need to calculate the total number of slices needed. Since there are 38 guests and each pie has 8 slices, the total number of slices needed is 38 multiplied by 1, which is 38. To find out how many pies we need to buy, we divide the total number of slices needed by the number of slices in each pie. So, 38 divided by 8 equals 4.75.
Since we can't buy a fraction of a pie, we need to round up to the nearest whole number. Therefore, we need to buy at least 5 pies to ensure each guest gets one slice of peach pie.
The correct option is B) 38>8p.
