Students from the local high school are selling tickets to the annual carnival. Adult admission is $5 and child admission is $2.50. On the first day
of the carnival, they sold 440 tickets totaling $1900. Which equations can
be used to represent this situation?

Google it that might work

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
