At the dog show, there are 4 times as many boxers as cocker spaniels. If there are a total of 30 dogs , how many are cocker spaniels
\(boxers = 4\times cspaniels\\ boxers+cspaniels=30\\ 4\times cspaniels + cspaniels = 30\\ 5\times cspaniels = 30\\ cspaniels = \dfrac {30}{5}=6 \\ boxers = 4\times 6 = 24\)
