Answer:
Option b
Step-by-step explanation:
To represent this proportion using fractions, let the numerators be the number of waffles sold and denominator, the number of sugar cones.
Thus, the proportion that can be used to represent the cone sales is
14/6 = 7/3
70 + 7p = 9p
70 = 9p - 7p
70 = 2p
70/2 = p
35 = p
