Joanie runs the concession stand for the school's baseball games. At each game, the best selling items are pretzels and hot dogs

Answer:

Number of hot dogs sold= 48

Number of pretzels sold= 33

Step-by-step explanation:

Designate 'h' for the quantity of hot dogs and 'p' for the quantity of pretzels sold today by Joanie.

It is given that:

She sold 15 more hot dogs than pretzels and made $195 overall.

This situation can be articulated as:

•  h=p+15 which can also be arranged as:

          h-p=15------------(1)  

• 3h+2p=195--------(2)

(Given that pretzels are priced at $3 each, while hot dogs are $2 each)

Now, we will solve these two equations to determine h and p.

Using substitution, we insert the expression for h from equation 1 into equation 2:

2(p+15)+3p=195

2p+30+3p=195

5p+30=195

5p=195-30

5p=165

Thus, p=33.

Then, for h:

h=33+15

h=48.

Consequently, Joanie sold 48 hot dogs

and 33 pretzels
