1. a catering company’s recipe for salad uses a ratio of 2 c of dressing to 4 lb of vegetables. draw a model for the ratio. write the ratio of dressing to vegetables as a reduced fraction.

2 cups to every 4 lbs.

1. 2c of dressing to 4lb of vegetables

Then d / v = 2/4 = 1/2 => d = v/2

Now you can make a table

v     d 

2    1

4    2

6    3

8    2

And you can draw a line for the points (2,1); (4,2); (6,3), (8,4) ... the slope of the graph is the ratio = 1/2

b) I already did it above as part ot the explanation: d/v = 1/2

A= b/2 because u simplying both sides of equation
