Answer:
I think it's $59.37
because there are five friends and there is 5% taken away form what they really payed so you would do,
5*5=25 as a percentage it would be .25/25%
so..25%+$47.50=59.37500
71/2 can also be written as 15/2, so divide 15/2 by 3/4. When you divide fractions you flip the second fraction and multiply it, so now it would be 15/2 X 4/3, so you would get 60/6 which is 10!
The roast was 82.2degrees Celsius when it was taken out of the hardwood smoker
It would of taken 80 mins for it to cool from 180 to 140
As every 20 mins it would decrease it's temperature by 10degrees C so it would be
80mins for it to reach 140 from 180
If you do 4*5, it will equal 20.
