18 double dip cones and 42 single dip cones
Work Step by Step
We first write the word problem as an equation. Next, we solve the equation using substitution. Doing this, we find:
$$ x+y=60 , 2.5x+4.15y=179.7 \\ \frac{5}{2}\left(60-y\right)+\frac{83}{20}y=\frac{1797}{10} \\ y=18 \\ x=60-18 \\ x=42$$
