Question

At an amusement park, a vendor attempts to guess a person's weight. If they are not within 3 pounds, the person will win a prize. If a person weighs 168 pounds and the vendor makes a guess of x pounds, which expression represents the number of pounds a guess is away from the actual weight?

Answer 1

Answer:

168-x < 3 or x>165

Step-by-step explanation:

If the guess is correct then x must be equal to 168 pounds. Mathematically,

168=x

168 -x= 0

But when x≠ 168 the expression becomes

168-x < 0

or

168-x < 3  because the guess has to be within 3 pounds to get the prize.

Solving this would give a value of x equal to 165 meaning if x is less than 165 he will not get a prize.

168-x < 3

168-3< x

165 < x

x>165
