The scale length is 9cm and the scale is 6cm/15ft which is 3cm/5ft, so we can say:
9cm(5ft/3cm)=15ft for the length
If you wanted the width too...
4cm(5ft/3cm)=20ft/3 (6'8", 6ft 8in)
I have no idea what it is but I’m guesting 5
Here are formulas we choose from
Increasing: y = a (1 + r)x Decreasing: y = a(1 - r)x
we want increasing
422000(1+.12)^5
743,708 (you don't want the decimals because you can't divide a human...)
I don't even know for real
The answer to number 8 is b
