Arecipe calls for 3 cans of tomato sauce. fawn wants to make 40 percent fewer servings than the recipe makes. which expression represents how many cans of tomato sauce fawn shouod use. explain how you got the answer
2/5 x 3

3/5 x3

7/5x3

8/5x3

8/5x3 this is the answer

I may not be a cook, but i know that the number of servings you want is directly proportional to the amount of tomato sauce you need. in other words, if you want half the amount of servings, then you need half the amount of tomato cans. 40% fewer means you want 60% of the servings which means you need 60% of the number of cans need for 1 serving. therefore, you need:
(60/100)(3)
(3/5)(3) so the answer is choice (b)
 
btw im assuming choice b is the 2nd one so yea...
 
anyways, let me know if you have any questions!

Ithink its 126 hope its
