Answer:
18 machines
Step-by-step explanation:
9 machines give 24 mins... You need to reduce the time by half by adding using double the machines..
So 9×2=18
75%
You need to find the total number of votes first. Just add 13 and 39 which would equal 52.
Then divide the number of people in favour by the total number of voters and multiply by a 100 to find the percentage.
39 + 13 = 52
39/52 = 0.75
0.75 x 100 = 75.0
