Question

PBR - (pls give the formula and full solution)

Answer 1

Answer:

I'm in class so I'll answer what I can!

1. okay so 25%=40 so to get to 100% we need to multiply 25% by 4 and so we so the same with the number 40x4 equals 160cm

2. so 8k from 20k think of 10k as 50% so it's around 5 per 1k so 8k would be 40% and so 60% would have been spent

3. (I might edit this one later I'm in class :(()

4. so 200cm last year and 240cm this year so it gre by 40cm so it'd be 20% (200=100% so that means it's twice as much as what the % would be!)

5. so 60 is 40% so 30 is 20% so just add up from there 20 x 5 = 100% so 30 x 5 = 150km
