Answer:
C(-2) = -9
Step-by-step explanation:
Step 1: Define
C(x) = -3x² - 3x - 3
C(-2) = x = -2
Step 2: Substitute and Evaluate
C(-2) = -3(-2)² - 3(-2) - 3
C(-2) = -3(4) + 6 - 3
C(-2) = -12 + 6 - 3
C(-2) = -6 - 3
C(-2) = -9
Answer: it will take 5 months for both gyms to cost the same.
Step-by-step explanation:
Let x represent the number of months for which the total cost of gyms are the same.
Gym A charges a new member fee of $65 and $20 per month. This means that the cost of using gym A for x months would be
20x + 65
Gym B charges a new member fee of $25 and $35 per month but you get a discount of 20% monthly.
20% of 35 is 20/100 × 35 = 7
The monthly charge would be
35 - 7 = 28
This means that the cost of using gym A for x months would be
28x + 25
The number of months that it will take for the cost of both gyms to be the same would be
20x + 65 = 28x + 25
28x - 20x = 65 - 25
8x = 40
x = 40/8 = 5
