To write the equation, you can start with the answer of $680. She receives $400 + $20*plans sold: 400 + 20p = 680 20p = 280 p = 14 {$400 + $20 * 14 = 680} Sam sold 14 plans to make a total of $680.

I believe the answer is A because it doesn’t make sense lol.
and number b makes sense because if you distribute you’d get 2x+2
number c makes sense as well because no matter the value of x there will be addition in the equation
and number d also shows that the question is equivalent because any value of x makes them equivalent for example pretend x=5 2(5+1) —> 2(6) = 12
2(5) + 2—> 10+2= 12
Therefore the expression is equivalent
and the best answer to this question is A
