At the ice cream parlor, sundaes cost $4.25 and waffle cones cost $3.75.You and your friends have $50 to spend. Your group buys 5 sundaes. How many waffle cones can you purchase?

You can buy 7 waffle cones.

Step-by-step explanation:

Let sundae = x

Let waffle cones = y

4.25x + 3.75y ≤ 50

4.25 (5) + 3.75y ≤ 50

21.25 + 3.75y ≤ 50

3.75y ≤ 28.75

y ≤ 7.666666666

* round to the nearest whole to get 7

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
