four teenagers collected a total of £64 for charity. each teenager collected a whole number of pounds. the modal amount collected was £16. the range of the amounts collected was £2. work out how much each teenager collected?
please someone answer
Had they collected £16 each, the mode would have been £16 but the range would have been £0
So two of them must have been £2 apart
£16, £16, £15, £17
Tutors come online at different times of the day, so you won't necessarily get immediate answers.
With 4 teens, at least two must have collected the modal amount 16 + 16.
64 - 32 = 32
With range of only 2, the remaining two must be one above and one below the mode.
