Problema Solution
Margarine is sold in either 250g or 400g packs. A hotel ordered 19.6 kg of margarine and received 58 packs. How many of each type did the hotel recieve?
Answer provided by our tutors
let 'x' represent the number of 250g packs received, then '58-x' represents the number of 400g packs received
250g = 0.25kg
400g = 0.4kg
19.6kg = 0.25x + 0.4(58-x)
solving for 'x' we have x=24
58-24 = 34
the hotel received 24 packs of 250g margarine and 34 packs of 400g margaine
