Answer:
$48.76
Step-by-step explanation:
So, Sara bought the pair of shoes for $46 due to a discount.
Sales tax was 6% or 0.06. In other words, she had to pay 0.06(46)=2.76 for tax.
Thus, the total amount Sara paid for the shoes is $46+$2.76=$48.76
They must sell, 30 cups of lemonade. How I got my answer.
Since it cost $1.20 to start, and a cup of lemonade cost $0.6 to make and there selling them at $0.10 each. So we know they are making a $0.4 profit off of each cup of lemonade. We now have to multiply 4×30=120.
I hope this helps!
Answer:

Step-by-step explanation:
This scenario can be modeled using an exponential growth equation.
The exponential growth equations have the following form:

Where P is the population in year t
p is the initial population at t = 0
r is the growth rate
t is the time in years.
In this case we know that the current population is 13,000 and that the growth rate is 11%
So

The equation that models this scenario is:


The answer to this is ten.
