Answer:

2,048 cells

Step-by-step explanation:

Number of cells after 1 hour = 4 * 2 = 8

Number of cells after 2 hours = 8 * 2 = 16

Number of cells after 3 hours = 16 * 2 = 32

Number of cells after 4 hours = 32 * 2 = 64

Number of cells after 5 hours = 64 * 2 = 128

Number of cells after 6 hours = 128 * 2 = 256

Number of cells after 7 hours = 256 * 2 = 512

Number of cells after 8 hours = 512 * 2 = 1,024

Number of cells after 9 hours = 1,024 * 2 = 2,048

1. Your total cost if 11.50 dollars.
It says that you ordered pancakes and a fruit cup
Pancake costs = x
Fruit cup cost = 1.50 dollars
you leave a tip = 15%

The equation would be:
=> (1.50 + x) .15 = 11.50 dollars
=> x = 11.50 – 1.50 x .15
=> Now, let’s find the cost of the pancake
=> 11.50 - 1.50 fruit cake = 10
=> 10 x .15 tip = 8.5
Thus, the price of the pancake is 8.5
