A savings account earns 15% interest annually. What is the balance after 8 years in the savings account when the initial deposit
natita [175]

The balance after 8 years is $22,942.67

<h3>What is the balance after 8 years?</h3>

We know that the savings account earns 15% annually, and the initial deposit is $7500, then the balance as a function of time in years is:

B = $7500*(1 + 15%/100%)^t

B = $7500*(1.15)^t

The balance after 8 years is what we get when we evaluate the above function in t = 8, so we get:

B = $7500*(1.15)^8 = $22,942.67

So the correct option is the last one.

Which ordered pair would form a proportional relationship with the point graphed below?
vampirchik [111]

Hey there! I'm happy o help!

To get from 60 to -20, you multiply by -1/3. This is our constant of proportionality. Let's see which points below follow this.

-10(-1/3)=3 1/3≠30

30(-1/3)=-10≠-15

-30(-1/3)=10

80(-1/3)=-26 2/3≠-30

Therefore, the correct answer is (-30,10).

Have a wonderful day! :D
