Argyle has $1000 in his savings account.
He wants to save more money. He’s looking to investment plans. Under plan a, he will increase his account balance by $300 a year. Under Plan B, he will increase his account balance by 15% each year. How much more when he say with Plan B after 10 years?

Argyle has $1000 in his savings account.

He wants to save more money. He’s looking to investment plans. Under plan a, he will increase his account balance by $300 a year. Under Plan B, he will increase his account balance by 15% each year. How much more will he save with Plan B after 10 years?

$45

Step-by-step explanation:

First, let's determine the amount he will have after 10 years with plan A:

$1,000+($300*10)= $1,000+$3,000= $4,000

Then, to determine the amount Argyle will have after ten years under plan B you can use the following formula:

FV= PV(1+i)^n

FV= future value

PV= present value= 1,000

i= interest rate= 15%

n= number of periods= 10

FV= 1,000*(1+0.15)^10

FV= 1,000*4.045

FV= 4,045

Now, you have to find the difference between the amounts you will get with each plan:

4,045-4,000= $45

Argyle will save $45 more with Plan B after 10 years.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
