The Biology Club plans to sell plants as a fundraiser. They found a supplier
that charges a $25 delivery fee plus $8 per plant, but the entire bill must be paid in
advance.
a. The club has only $475 in its bank account. Write an inequality that represents the
fact that the club can spend no more than this amount on plants.
b. Use substitution to determine whether the club has enough money to order 50 plants

Respuesta :

The inequality that represents that the club can spend no more than this amount on plants is 8x + 25 ≤ 475

  • Delivery fee = $25
  • Cost per plant = $8
  • Number of plants = x
  • Amount in the account = $475

The inequality:

8x + 25 ≤ 475

  • If the club orders 50 plants

8x + 25 ≤ 475

  • Using substitution

8(50) + 25 ≤ 475

400 + 25 ≤ 475

425 ≤ 475

Therefore, the club has enough money to order 50 plants
