Answer:
C
Step-by-step explanation:
Hope this is right, this is what I got.
Fill in the values and calculate:
1/4 * 6 + 3*7 = 6/4 + 21 = 22 1/2
30 * 0.30 = 9
30 + 9 = 39
30 increased by 30% = 39
100/1200= x/100
cross multiply
(1200 * x)= (100 * 100)
1200x= 10000
divide both sides by 1200
x= 8.333% winning chance
LOSING CHANCE
100% - 8.333%= 91.667%
RATIO OF WINNING TO LOSING
100 tickets= winning chance
1200 total - 100= 1100 losing chance
100:1100
simplify by 100
1:11 odds of winning to losing
ANSWER: The chance of winning is 8.333% and the chance of losing is 91.667% or 1:11.
Hope this helps! :)
