How many tickets can I buy

Question

I have $25.00.  Tickets are $4.50  and $7.50 each.   Write an inequality and graph it that represents the number of $4.50 and $7.50 tickets I can buy.    

Answer 1

let x = number of tickets at $4.50 and y = the number of tickets to be sold at $7.50.  Remember you can spend up to but not more than $25.00.  Let the total cost of tickets sold at at $4.50 be represented as 4.50x, and the total cost of tickets sold at $7.50 be represented by 7.50y.

write the total cost equation:  4.5x + 7.5y ≤25  , create a table of values and graph
