Aconcession stand sold hamburgers, salted pretzels, and hot dogs at a basketball game. hamburgers were sold for $3.00, salted pretzels were sold for $2.25, and hot dogs were sold for $2.00. the total number of hamburgers, salted pretzels, and hot dogs sold was 144, and the total amount of money from these items was $354.25. if $82.00 was made just from selling hot dogs, how many salted pretzels were sold?

110

Step-by-step explanation:

Set hamburgers as h,

salted pretzels as p,

hot dogs as d.

h+p+d=144

(3.00)h+(2.25)p+(2.00)d=354.25

=>3h+2.25p+2d=354.25

we also know (2.00)d=82 => d=41

We make 3h+2.25p+2d=354.25 => 3h+2.25p=272.25

and h+p+d=144 => h+p=103

Set h=p-103

Substitution

3(p-103)+2.25p=272.25

3p-309+2.25p=272.25

(5.25)p=581.25

p=581.25/5.25=110.7142857

We round down =>110.
