Answer 2

Answer:

200

Step-by-step explanation:

Let the number of $1 drinks = x

Let the number of $3 drinks = y

so, x + y = 300 -----------------(1)

price generated selling x drinks = 1 * x = x

price generated selling y drinks = 3 * y = 3y

But total price sold = $700

Thus x + 3y = 700 -----------------------(2)

Solving equation 1 and 2 simultaneously, we have that:

y = 200

But recall that y = number of $3 drinks

Hence, answer = 200
