Ответ:
Number of hot dogs sold= 48
Number of Pretzels sold= 33
Step-by-step explanation:
Let 'h' be the number of hot dogs and 'p' be the number of pretzels that Joanie has sold today.
As it is given that:
Today she sold 15 more hot dogs than pretzels and made $195 in total sales.
i..e in terms of equation it could be represented as:
h=p+15 which could also be written as:h-p=15(1)
2h+3p=195(2)( since Pretzels are $3 each, and hot dogs are $2 each )
Now we solve the two equations above to find the value of h and p.
we will use the method of substitution to solve this system.
Substitute the value of h in terms of p from equation 1 in equation (2) to obtain:
2(p+15)+3p=195
2p+30+3p=195
5p+30=195
5p=195-30
5p=165
p=33.
Now the value of h is:
h=33+15
h=48.
Hence, the number of hot dogs sold by Joanie= 48
and number of Pretzels sold by Joanie= 33
