7. the concession stand at a football game sells hamburgers and hot dogs. • hamburgers are sold for $5.50 each. • hot dogs are sold for $4.00 each. • the concessions stand sold a total of 140 hamburgers and hot dogs. • of the hamburgers and hot dogs sold, 3/5 were hamburgers and the rest were hot dogs. how much money did the concession stand make from the hot dogs that were sold?
Answer
# Explanation:
## Step1: Calculate number of hot - dogs sold
The total number of hamburgers and hot - dogs sold is 140. The fraction of hamburgers sold is $\frac{3}{5}$, so the fraction of hot - dogs sold is $1-\frac{3}{5}=\frac{2}{5}$.
The number of hot - dogs sold is $140\times\frac{2}{5}= 56$.
## Step2: Calculate money made from hot - dogs
Each hot - dog is sold for $4.00.
The money made from hot - dogs is $56\times4 = 224$.
# Answer:
224
