Problema Solution
adidas sold 300 pairs of shoes. the number sold at market stalls is thrice the number sold at department stores, and the number sold by foot salesman is one-eight the number sold at market stalls. How many pairs of shoes were sold from the market stalls?
Answer provided by our tutors
let 'x' represent the number sold at department stores, then '3x' represent the number sold at market stalls and '(1/8)3x' represents the number sold by foot salesman
300 = x + 3x + (1/8)3x
solving for 'x' we have x=68.57
this indicates an error in the problem statement since the department stores would not sell "0.57" of a shoe, but nonetheless we continue...
68.57*3 = 205.71
the number sold at market stalls was 205.71... again, this type of problem should typically result in an integer answer, so there is probably some error in the problem statement
