108=103e^(5k)

108/103=e^(5k)  take the natural log of both sides

ln(108/103)=5k

k=ln(108/103)/5

k≈0.00948

P=103e^(12*0.00948)

P≈115 million (to nearest million)

The marker cost 1/3 as much as the pen, the pen cost 1/3 as much as the book, the book cost 1/3 as much as the game. How much do
natulia [17]

Answer:

Step-by-step explanation:

We'll need the actual prices of one of the objects to figure it out...

but I've worked it out here in relation to each object....

Marker = 1/3 x cost of the pen

Marker = 1/3 x 1/3 x cost of book = 1/9 x cost of the book

Marker = 1/3 x 1/3 x 1/3 x cost of game = 1/27 x cost of the game

This probably isn't what you're looking for, but maybe it'll help?

Answer:

x = 9

Step-by-step explanation:

First equation = 4x - 8

Second equation = 7x - 35

Seperate the equation with an equal sign to make it an equality equation and solve for X so :

4x - 8 = 7x - 35 (Given)

-3x - 8 = -35 (Subtraction property of equality)

-3x = -27 (Addition property of equality)

x = 9 (Division property of equality)

Solution:

x = 9
