Ans: 93
Explanation:
The following information is given in the question:
1) Total of 209 salads and drinks.
2) salads for $6.50 each and drinks for $2.00 each; and total revenue was $836.50
Now let us assign variables to the following entities:
1) Salad = S
2) Drinks = D
From the information given above,
1. S + D = 209 (total number of salads and drinks) -- (A)
2. 6.50S + 2.0D = 836.50 (total revenue equation) -- (B)
From equation (A):
D = 209 - S
Substitute the above equation in (B)
(B) => 6.5S + 2(209 - S) = 836.5
=> 6.5S + 418 - 2S = 836.5
=> 4.5S = 418.5
=> S = 93
Ans: Salads sold that day = 93.
