Answer:
To make $175, he has to sell 644 hotdogs.
Explanation:
Lets do this together step by step.
To calculate the cost of a single hot dog, divide the profit recieved by the number of hot dogs.
So that would be 14/56 which would result in $0.25.
Now we know that 1 hot dog = 25 cents.
Now, all of the money we receive ( $175) comes from selling a certain number of hot dogs.
We can see that in order to calculate how many hotdogs we could buy with this sum of money, we would need to divide the total by the price of each hot dog.
175/0.25 = 700 ( Thats quite a lot.)
700-56 =644
He has to sell 644 hotdogs to earn $175.
