A recipe calls for 2 1/2 cups of flour. The recipe makes 5 servings. How many cups of flour are needed to make 7 servings. 35
14
3 1/2
12 1/2

3 1/2 cups of flour

Step-by-step explanation:

I used this equation:

2.5/5 = x/7

Then I cross multiplied:

2.5 * 7 = 5x

After I found out that x = 3 1/2

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
