Answer:
$5,552.26
Step-by-step explanation:
First, set up an equation using exponential decay
Let y represent the cost and let x represent the number of years
y = 15,000(0.78)^x
Plug in 4 as x, and simplify:
y = 15,000(0.78)^4
y = 5,552.26
So, in 4 years, the car will be $5,552.26
21
Step-by-step explanation:20+1=21X2+5+3=50
yes
~Subtract 12 from both sides
3/4x + 12 − 12 = 24 − 12
~Simplify
3/4x = 12
~Multiply both sides by 4/3
3/4 * 4/3 = 12 * 4/3
x = 16
Hence, the correct answer is [ b. 16 ]
Best of Luck!
