B. $0.80 per hot dog
C. $1.25 per hot dog
D. $2.50 per hot dog

Answer 1

Answer: Hence, option 'C' is correct.

Explanation:

Since we have given that

A deli sells 2 hot dogs for $2.50

i.e.

Cost of 2 hot dogs = $2.50

And we need to find the constant of proportionality of dollars per hot dog, for which we'll use unitary method.

So,

Cost of 1 hot dog is given by

$\frac{2.50}{2}=\ 1.25$

So, Cost of per hot dog is $1.25.

Hence, option 'C' is correct.
