Answer:
The change after five years is equal to -$100
Step-by-step explanation:
If the insurance payment is equal to P = N dollars, where P is a real number, we know that after one year, the payment decreaces by $20, so the new payment is:
P = N - $20
Then, after 5 years, the $20 dollars are discounted five times, so the payment will be:
P = N -5*$20 = N - $100
Then the total change after 5 years is equal to those $100 that are being subtracted in the last equation.
The answer is 3 .
x=3
Here's why :
4x+4=16
You get rid of the four by adding -4 . You add -4 to the other side .
4+-4=0
16+-4=12
4x=12
Then you divide by 4 , because you want to find the value of one x.
4x/4=x
12/4=3
x=3
hope it helps !
