We are given

The student council earned $1.25 for every cup of hot chocolate it sold

and $0.75 for every cup of apple cider it sold

total number of cup is 375

we have equation as

[tex] x+y=375 [/tex]

[tex] 1.25x+0.75y=393.75 [/tex]

The above equation is of total cost equation

We can see that first term is 1.25x

and we have

The student council earned $1.25 for every cup of hot chocolate

so, to find total cost of hot chocolate , we multiplied 1.25 with x

that's why

x must be the number of cups of hot chocolate sold

Hence,
