Theo:James 18+4.5x : 4x, where x = number of weeks
We can assume week 0 = 18:0 as Theo and James start off with £18 and £0 respectively. Week 1: 22.5:4 Week 2: 27:8 Week 3: 31.5:12 Week 4: 36:16 Week 5: 40.5:20 Week 6: 45:24, which divided by 3, simplifies to 15:8, therefore it took 6 weeks.
surely in the first week they have 0 and 18 but nevertheless even if i did get that wrong i should get 2/3 for working
Who got 50.6 for the perimeter of ths pentagon? Yeah I got roughly that but it didn't specify to round up or not so I just put the full value in the calc
I did too. I’m guessing you used SOH CAH TOA to work it out?
