Final answer:
To find out how many peas the dinner ladies need to cook, we multiply the average number of peas given to each pupil by the total number of pupils eating school dinners. In this case, the dinner ladies need to cook 8500 peas.
Step-by-step explanation:
To find out how many peas the dinner ladies need to cook, we need to multiply the average number of peas given to each pupil by the total number of pupils eating school dinners.
Given that each pupil is given an average of 34 peas and there are 250 pupils eating school dinners, we can calculate the total number of peas needed as follows:
Total number of peas = Average number of peas per pupil x Number of pupils
Total number of peas = 34 x 250 = 8500 peas
So, the dinner ladies need to cook 8500 peas.
