Question

A hot dog costs $1 at the ballpark. Which equation shows the total cost, C, of n hot dogs?
⚫️n = 1c
⚫️n = 1+c
⚫️c = 1n
⚫️c = 1 + n

Answer 1

C=1n

Step-by-step explanation:

So first you look for keywords, the most noticeable one is "total cost." C will be at the end of the equation.

C= ? + ?

Then, each hot dog costs $1 which means no matter how many hot dogs there will be, it will be multiplied by the cost. So, the answer is:

c=1n

Answer 2

c=1n is the answer because the cost of hotdogs equals the price times the number of hotdogs
