Eva has 65 flowers for a big party decoration. In addition, she is planning to buy some flower arrangements that have 20 flowers each. All of the arrangements cost the same. Eva is not sure yet about the number of flower arrangements she wants to buy, but she has enough money to buy up to 5 of them. Write a function rule to describe how many flowers Eva can buy. Let x represents the number of flower arrangements Eva buys. Find a reasonable range for the function. HELP!!!!!!
