Fungai steps into the supermarket to buy a candle. A candle costs 29 cents. She has a $2 note, and the shopkeeper has 5 cent and 6 cent coins only in his till. If Fungai is to get her change in these denominations,
what is the largest product she can obtain after multiplying the number of 5 cent coins by the number of 6 cent coins in her change?
The solution starts with the equation 6x + 5y = 171. Where did they get 171

Best ResponseYou've already chosen the best response.26s + 5f = 171 M = sf ; f= (6s +171)/5 M = s[(6s +171)/5] M = (6s^2 +171s)/5 M' = (12s +171)/5 M' = 0 when s = 171/12 = 14.25; so its close to that when six cent = 14 or 15 looks to be the options; and Hark decided that fate :)

Best ResponseYou've already chosen the best response.0My logic goes as follows: one 5 cent coin and one 6 cent coin together make 11 cents If we divided 171 by 11, we get Quotient as 15 and remainder is 6 This means that if she gets 15 coins of 5 cents and 15 coins of 6 cents then remainder is 6 cents So we can say that if she has 15 coins of 5 cents it is = 75 cents and 15 + 1 coins of 6 cents ie 16 coins of 6 cents it is = 96 cents 75 + 96 = 171 so product of number of coins is 15 x 16 = 240 Hope it explains how I arrived at the solution......!!!
