Answer:
93
Step-by-step explanation:
x = 4, y = 5
3(4x + 3y)
= 3(4(4) + 3(5))
= 3(16 + 15)
= 3(31)
= 93
Answer:
A new car costs $23,000. The value decreases by 15% each year.
An exponential model to represent the car's value after t years:
y = 23000 x (1 - 15/100)^year
= 23000 x (0.85)^year
Hope this helps!
