The Binary Ice Cream Shoppe sells two flavors, vanilla and chocolate. On friday, the ratio of vanilla cones sold to chocolate cones sold was 2 to 3. If the store had sold 4 more vanilla cones, the ratio of vanilla cones sold to chocolate cones sold would have been 3 to 4. How many vanilla cones did the store sell on Friday?

a) 32

b) 35

c) 42

d) 48

E) 54

V/C=2/3

3V=2C, V = 2/3C

If the store had sold 4 more vanilla cones, the ratio would be 3/4.

So (V+4)/C = 3/4, substitue V = 2/3C into the equation, I get C = 48, V = 32.

A is my answer
