Question

A food truck sells salads for $6.50 each and drinks for $2.00 each. The food truck's revenue from selling a total of 209 salads and drinks in one day was $836.50. How many salads were sold that day?

Answer 1

Number of salads sold in that day = 93

Step-by-step explanation:

Using algebra we have,

Let salad = X

Drinks = Y

Now Total units = 209

That means

X + Y = 209

Y = 209 - X

Also

6.5X + 2Y = 836.50

Putting above value of Y in this equation we have

6.5 X + 2(209 - X) = 836.50

6.5X + 418 - 2X = 836.50

4.5X = 836.5 - 418 = 418.5

X = 418.5/4.5 = 93

Therefore X = Salads = 93 in units

Number of salads sold in a day = 93 units
