Suppose that you are running a concession stand when a person gives you $18 and asks for six soft drinks and as many hot dogs as the remaining money will buy. If soft drinks are $1.00 and hot dogs are $1.75, what is the maximum number of hot dogs the person can buy?

the max number of hot dogs he can buy is 6 with change left

Step-by-step explanation:

18.00 - 6.00 = 12.00 / 1.75 = 6.8

Answer: 6 hot dogs

Step-by-step explanation:

The person gave you $18, first, we will charge the six soft drinks, that each one costs $1

So the six drinks cost $6

the remaining money is $18 - $6 = $12

Now, with the $12 the customer wants to buy hot dogs, that each cost $1.75

The number of hot dogs can be obtained by dividing the total money by the price of a hot dog:

N = $12/1.75 = 6.8

But you can not buy an 0.8 of a hot dog, so we must round to the whole number:

N = 6

So the maximum number of hot dogs that the money can buy is 6
