Answer:
C
Step-by-step explanation:
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 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
So the answer must be C
