Person a sells a bicycle to person b at a profit of 20% and person b sells it to person c at a profit of 25%, if person c pays 1500, what did person a pay for it?

so if person a sell the bicycle to person b at a profit of 20% and person b sell it to person c for a profit of 25% then you got to multiply 20% and 25% together and you'll get 0.05 then divide 1500 into 0.05 and you'll get 30,000 and that's your answer

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
