How much should Kim deposit (one time) in an account earning 1% per month (so r = 12% and k= 12)to
have a $5,000 down payment for her new car after 4 years?

Using the formula;

A = P(1 + rt)

A = Amount i.e. $5000

P = Principal or Initial payment

r = rate i.e. 12%

t = 4 years

5000 = P(1 + 0.12 × 4)

5000 = P(1 +0.48)

5000 = P(1.48)

P = 5000 / 1.48

= $3378.378

= $3378

The answer would be C) –3x and –6x

Step-by-step explanation:

using the headers for both the top and left side of the diagram, we can see that we need to add a value for when x is multiplied with -3, and when x is multiplied with -6, thus C is our answer
