Round 23

Date released: August 29th, 2001.
Date rewarded: September 12th, 2001.

The Fontaine sisters are seamstresses by trade. They have been commissioned to create as many 2 by 3 feet rectangular Jolly Roger flags as they can for the pirates in their village, so Loretta Fontaine has gone out to buy cloth to embroider.

Dark cloth costs 150 Neopoints a foot and comes in a roll five feet wide. It can be bought in any length (even down to the inch). She has a total of 1,260 Neopoints to spend on the cloth.

How many WHOLE Jolly Roger flags will they be able to make???

Number of feet of the Dark cloth that the Fontaine sisters can buy:
1260 / 150 = 8.4 ft

The area of the bought cloth:
8.4 * 5 = 42 ft²

Number of possible whole flags with that area of the cloth:
42 / (2 * 3) = 7

However, if we check the below figure, the is no way to make 7 flags from the cloth (each flag must have 2 ft x 3 ft dimension). The sisters can make maximum 6 flags from the cloth.

Therefore, the Fontaine sisters can make 6 whole Jolly Roger flags.
