Answer:
It would be 8
Step-by-step explanation:
20% of 40 is 8
x - y = 14
given the ratio x : y = 5 : 3
then let x = 5x and y = 3x, hence equation can be expressed as
5x + 3x = 56
8x = 56 ( divide both sides by 8 )
x = 7
Hence x = 5 × 7 = 35 and y = 3 × 7 = 21
Thus x - y = 35 - 21 = 14

Answer:
174 people preferred drinking water.
Step-by-step explanation:
Given that:
A total of 450 males and females were surveyed.
203 were males.
Number of females = 450 - 203 = 247 females
247 females were surveyed.
Now, we will find the number of females who prefer water.
Let,
x be that number.
Total number of females = Soda + Iced tea + Lemonade + Water
247 = 28 + 44 + 67 + x
247 = 139 + x
247-139 = x
x = 108
Number of people who prefer water = 108 + 66 = 174
Hence,
174 people preferred drinking water.
