Jessica has eaten 3 1/2 hot dogs of the 10 hot dogs she recently found in her freezer. What percent of the hot
dogs has she eaten?

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)

answer: your answer is a

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.
