**Claire**, Thursday, May 29, 2014 at 10:35pmFor a) you just need to divide that amount of space each girl has by 100 and times it by the total area of the house they are renting. then you times the percentage you get by that cost of rent.

eg: Laura = 20/100x50

= 40%

= 40/100*900

= $360

For b) you calculate their food and water and electricity amount to make them per fortnight, add them and divide by three then you add that on top of the rent
