Jenny invests $2,000 at an interest rate of 5%. the amount of money, ma, in jenny's account after t years can be represented using the equation ma. = 2000(1.05)^t. if jenny would have invested the same amount of money at the same interest rate four years ago, the equation representing the amount of money, mb, in her account would be represented using
the equation mb= 2000(1.05)^t+4. which of the following is equivalent to mb?

The Amount after 4 years is $2430  .

Step-by-step explanation:

Given as :

The principal amount investment = p = $2000

The rate of interest applied = r = 5%

The time for investment = t years

Let The Amount after t years = $A

From Compound Interest method

Amount = Principal ×

Or, A = p ×

Or, A = $2000 ×

Or, A = $2000 ×

So, The Amount after t years =   A = $2000 ×

B) The principal amount investment = p = $2000

The rate of interest applied = r = 5%

The time for investment = t = 4 years

Let The Amount after t years = $A

From Compound Interest method

Amount = Principal ×

Or, A = p ×

Or, A = $2000 ×

Or, A = $2000 ×

i.e A = $2000 × 1.215

Or, A = $2430

So, The Amount after 4 years =   A = $2430

Hence, The Amount after 4 years is $2430  . Answer

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
