Afood 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?
a 77
b) 93
c) 99
d) 105

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.

43

step-by-step explanation:

not sure if this is supposed to be a trick question. 43 is the only one that makes any sense.
