The summer after sophomore year, haley nannied for a family and earned $2000. she
decided to save it all and deposit it into an account earning 5.8% interest compounded
monthly. when haley finished college, 6 years later, she decided to use the money to put
deposit on a car. how much money did haley have?

$2,830.09

Step-by-step explanation:

First, convert R as a percent to r as a decimal

r = R/100

r = 5.8/100

r = 0.058 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 2,000.00(1 + 0.058/12)(12)(6)

A = 2,000.00(1 + 0.004833333)(72)

Summary:

The total amount accrued, principal plus interest, with compound interest on a principal of $2,000.00 at a rate of 5.8% per year compounded 12 times per year over 6 years is $2,830.09.

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
