Karen opens a savings account with $1500. she deposits $100 every month into the account that has a 0.85% interest rate, compounded annually. if she doesn’t withdraw any money, what will the account balance be in 10 years?

Formula is

D represents  the amount of a regular deposit

r  represents the annual interest rate  

m  is the number of equal compounding period  

t the time in years,

F is the future value

D = 100, r= 0.85%= 0.0085, m= 1  and t=10

m*t= 1*10 = 10

Plug in all the values in the formula

= 1039.13

Karen opens a savings account with $1500

Already he has 1500

So account balance = 1500 + 1039.13 = $2539.13

78.59 is the mean

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
