182 because 14/4 equals to 3.5 and then you do 3.5*15 which is 182

Ghella [55]

Remark

There are two ways to do this. You can graph the equations (which I have included at the end of the question using Desmos) or you can solve it algebraically which in this case is going to be slightly painful.

Algebra

Multiply the first equation by 4 and the second by 3

<em><u>First Equation</u></em>

4 [3x + 4y = 16]

12x + 16y = 64             (3)

<em><u>Second Equation</u></em>

3 [-4x - 3y = - 19]

- 12x - 9y = - 57           (4)

Add (3) and (4)

12x + 16y = 64

<u>- 12x - 9y = -57 </u>           Add

7y = 7                           Divide by 7

y = 1

Solve for x

3x + 4y = 16         Let y = 1

3x + 4(1) = 16

3x + 4 = 16           Subtract 4

3x = 12                 Divide by 3

x = 12/3

x = 4

Answer

(4,1) just as the graph suggests.

Given

If one start with one square unit it takes 100 days

i.e. At second day it is 2 unit

third day 2^2

at n th day 2^{n-1}

at 100 day 2^{99} square unit

If we start with 2 square units it would take

2^n for n days

2^n=2^{99}

n=99\ days
