Question

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

Answer 1

93

Explanation:

s= salads d= drinks

$6.5s + $2d = $836.5

s + d =209

s = 209-d

6.5 (209-d) + 2d = 836.5

1358.5 - 6.5d + 2d = 836.5

-4.5d = -522

d = 116

s = 209 - 116 = 93
