Answer:
She can buy 25 boxes of pasta with $65
Step-by-step explanation:
This question is actually very easy if you forget about all of the unnecessary information. They throw a lot of unnecessary information like they telling you that there are 12 ounces of pasta in each box. You never need that information. My point is that watch out for unnecessary info. Other than that, you can simply multiply 13 (price of 5 boxes) by 5 and get 65. That means that just multiply 5 by 5 and you will see that she can buy 25 boxes of pasta with $65.
You can divide 950 by 19 to get the speed in ft/min:
