Answer: $134.40
Step-by-step explanation: Just find 80% of 168. That is because 100 - 20 is 80. The question says 20% OFF.
Answer: probability = 0.506
Step-by-step explanation:
The data we have is:
Total people: 205 + 160 + 40 = 405
prefer cats: 205
prefer dogs: 160
neither: 40
The probability that a person chosen at random prefers cats is equal to the number of people that prefer cats divided the total number of people:
p = 205/405 = 0.506
in percent form, this is 50.6%
True. To solve for y you have to subtract 2 from both sides of the equation.
X=hamburgers
y=hotdogs
3y+2x=8.00
AND
2y+3x=8.25
Now we've got a system of equations!
Choose a method to solve it, and I think you'll be good from there.

BEST OF LUCK:)
2y/5 is the same thing as 2/5 times y so
14=2/5(y) then you divide both sides by y and you get
14/y=2/5 then from there multiply both sides by 1/14 to get
y=0.03
