If you assume that the amount that each pupil donates is evenly distributed between $1.50 and $2.20, then the average amount donated by each pupil is ($1.50 + $2.20) / 2 = $1.85.

There are 42 pupils, so half of them is 42 / 2 = 21 pupils

Thus, the estimated amount donated by half of the pupils is $1.85 x 21 = $38.85
