Answer:

1) 21

2) 28

3) 13

Step-by-step explanation:

According to the word problem, a=7 and b=4.

Now, we just plug in the numbers.

14 + 7 = 21

7 ⋅ 4 = 28

5 ⋅ 4 - 7 = 13

ANYTIME YOU SEE TWO VARIABLES (LETTERS) TOGETHER, THAT MEANS MULTIPLY THEM.

AN EXAMPLE OF THIS IS NUMBER 2.

Please answer the question and leave an explanation on how to solve each part. Thank you in advance!

The solutions are

  • it is going to take 15.9 months to raise 10000 dollars
  • You will have $37.31 after you have bought the car
  • The money deficit would be $37.31

<h3>How to solve the question</h3>

a. 10000 = 9359.08e(0.05)

e⁰⁰⁵ = 10000/9359.08

= 0.05 = ln(10000/9359.08)

= 1.325 years

convert to months = 15.9 months

Hence it is going to take 15.9 months to raise 10000 dollars

b. 9359.08 x e^(0.05 x1.25)

= 9962.69

10000 - 9962.69

= $37.31

You will have $37.31 after you have bought the car

c. The money loss and the deficit would be same as above $37.31

d. ln(e^a) = a

We can clearly see that the money cannot be raised in the 15 months from $ 9359.08. there is a deficit amount of $37.31
