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.

solve simultaneously
Step-by-step explanation:
make one of the equations x subject of the formula and the other equation y subject of the formula
y=8+2/5x....1
x=-5/3 + 2/3y.....2
substitute equation 1 into equation 2
x=5
y=10
