Which of the following situations cannot be modeled with the equation 5x – 15y = 335?
a.
randy earns $5 for each hour he works at his job, and spends $15 each time he goes out to dinner. he has $335 at the end of the week.
b.
a hamburger sells for $5 but costs $0.15 to make, giving a net income of $3.35.

d.
tommy earned points for 5 correct answers on a standardized test, but was docked for 15 incorrect answers for a point total of 335.

b)

Step-by-step explanation:

A) if we name x the number of hours he works and y the number of times he goes out, the equation would be 5x - 15y = 335.

B) The income would be the selling price minus the costs, this would be written as 5 - 0.15.

C) If x is the payment she gets per each sale  and y is the amount she losese when she doesn't sale, this would be: 5x - 15y = 335.

D) If x is the number of points per correct answers and y is the number of points she loses for incorrect answers, we get: 5x - 15y = 335.

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =
