Answer:
2400 inches or 2000 feet is the correct answer
there are 60 minuets in an hour, and 10 sets of 6 minuets, so you multiply 5 by ten to get 50
then you multiply 50 by 48 to get 2400
then you divide by 12 to get 2000 feet

O=out
I=inside
L=last
5a*5a+5a*-7+7*5a*7*-7
25a^2-35a+35a-49

Hope this helps!
use unitary method
for 5 it costs 330p
so for 1 choc it will cost 330/5
to get 9,
(330/5) =66
66 multiplied by 9 =594
therefore 9 will cost 594p
