Answer:
8 types of sandwiches.
Step-by-step explanation:
she has choices of :
1 turkey sandwich
1 roast beef sandwich
1 ham sandwich
1 white sandwich
1 white bread sandwich
1 American sandwich
1 swiss sandwich
1 colby cheese sandwich.
1. ratio = 2 c of dressing / 4 lb of vegetables
Use two variables: d for the number of c of dressing and v for the number of pounds 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
It is 2.4 x 2.5 which equals 6 the answer is 6
