Answer:
Total discounted cost: $442
Original total cost: $520
Explanation:
Part A:
When bringing cat to veterinary clinic, LeeAnn has to pay for the tests, medicine and appointment fee for each appointment.
Assume that the course requires x appointments
=> Cost for x appointment fee is: x*Cost per appointment
=> Total cost (t) = Costs for tests and medicines + x*Cost per appointment
=> t = 250 + 45x
Part B:
As LeeAnn got 25% discount off total cost, so that her updated cost is calculated in the following equation:
Updated cost = Original total cost - Original total cost x Discount percentage
= 250 + 45x - (250+45x) x 15% = 250 + 45x - 37.5 - 6.75x
= 212.5 + 38.25x
=> Equation of updated cost: Updated cost = 212.5 + 38.25x
If the treatment requires 6 appointments => x = 6
=> Original total cost will be: t = 250 + 45 x 6 = $520
=> Her total discounted cost will be:
Updated cost = Original total cost - Original total cost x Discount percentage = 520 - 520 x 15% = $442
