Test, Form 3A (continued)
Use the following information for Exercises 11–13.An animal hospital provides aid to sick and injured sea turtles. The cost of visiting the hospital for x number of visitors is shown in the table.
Admission Cost
Admission Ticket Cost ($)
weekday 7.50x + 5
weekend 15x + 10
11. The constants in each expression represent the amount of money that is donated directly to a specific turtle each month. What amount for each ticket is donated directly to a turtle?
12. Write an expression in factored form that is equivalent to the sum of weekday and weekend tickets.
13. Write an expression to show how much greater the cost is for a weekend ticket than a weekday ticket.
14. The side lengths of a triangle are (5x + 1), (6x - 10), and (6x + 2). Write and expression in simplest form for the perimeter of the triangle.
15. Write an expression in factored form that is equivalent to the expression 3 −
4 x + 24.
16. A rectangular playground has an area of 25x square meters. A rectangular swimming pool, adjacent to the playground, has an area of 55 square meters. Write an expression in factored form to represent the total area of the playground and the pool.
5525x
