The doubling time is a characteristic unit (a natural unit of scale) for the exponential growth equation, and its converse for exponential decay is the half-life. For example, given Canada's net population growth of 0.9% in the year 2006, dividing 70 by 0.9 gives an approximate doubling time of 78 years.
Known fact:
- $100 dollars for 8 hours of work --> $100 / 8hrs = $12.50 dollars/hrs
Two hours of work = $12.50 dollars/hr * 2hrs = $25 dollars
Six hours of work = $12.50 dollars/hr * 6hrs = $75
Ten hours of work = $12.50 dollars/hr * 10hrs = $125
fourteen hours of work = $12.50 dollars/hr * 14hrs = $175
Thus the answer is the bottom left choice.
6,256 is the answer to the question.
Answer:
1 ruler costs $0.60
Step-by-step explanation:
$20-$4.70=$15.30
Calculator =$7.50
3 Packs of Pens = $1.80 each
4 rulers= x each
$7.50 + 3($1.80) + 4x = $15.30
7.50 + 5.40 + 4x = 15.30
12.90 + 4x = 15.30
4x = 2.40
x = 0.60
