At the amusement park, the paddle boats have a sign posted: 2x+2y=500 Where x and y are the weights of the riders.

Which of the following can be the weights of the two riders?

A. (100, 200)
B. (240, 0)
C. (150, 340)*
D. (100, 150)

First of all, whoever made the sign did not take math, or he would have simplified

the message on the sign to
x+y = 250

Now, for which of the ordered pairs do the x and the y add up to 250 ?
Does your choice also work in the un-simplified version? It must!

Oh, Reiny my bad 2x+2y<500 Where x and y are the weights of the riders.

That how it suppose to be

So what ?

Wouldn't that simply change my question to ...
"For which of the ordered pairs do the x and the y add up to less than 250" ???

To determine which of the given options can be the weights of the two riders, we need to substitute the values of x and y from each option into the equation 2x + 2y = 500 and check if the equation is satisfied.

Let's go through each option and substitute the values:

A. (100, 200)
Substituting x = 100 and y = 200 into the equation:
2(100) + 2(200) = 500
200 + 400 = 500
600 ≠ 500
The equation is not satisfied, so option A is not correct.

B. (240, 0)
Substituting x = 240 and y = 0 into the equation:
2(240) + 2(0) = 500
480 + 0 = 500
480 ≠ 500
The equation is not satisfied, so option B is not correct.

C. (150, 340)
Substituting x = 150 and y = 340 into the equation:
2(150) + 2(340) = 500
300 + 680 = 500
980 ≠ 500
The equation is not satisfied, so option C is not correct.

D. (100, 150)
Substituting x = 100 and y = 150 into the equation:
2(100) + 2(150) = 500
200 + 300 = 500
500 = 500
The equation is satisfied, so option D is correct.

Therefore, the only option that satisfies the given equation is D. (100, 150).
