Answer:
11

Step-by-step explanation:
3 hrs to travel 45 miles downstream
4 hrs to travel 28 miles upstream
speed of boat in still water= s
speed of the current= c
added up the 2 equations, we get:
Since this is simple interest, there's a formula to calculate the interest. Once you find the interest you can add that back to the principal and get your total amount paid.
Here's the formula: Interest = principal * rate * time.
We don't know the interest of the loan or the extra money you have to pay on top of the 10,000 borrowed. Anyways, plug in what you got to find the interest.
Interest = 10000 * .03 * 6
Interest = 1800.
This is the extra amount you've to pay while also paying the 10,000 back. To find out the total amount, just add the interest to the amount borrowed which is the 10,000.
So, 10,000 + 1800 = $11,800. That's the total amount that you'll pay. Hope this helped!
The first thing that shoyuld be noted is that you have linear functions here : straight lines in your graph
It is a greater number (-3 > -12).
Think of it like this:
Subtract the negative value from any positive value, like 20.
20 - 12 = 8
20 - 3 = 17
As you can see, the equation involving -3 produces a larger number, meaning that the -3 took less value away. This makes it the greater number.
Answer: Option C. $13.90
Solution:
Approximate cost to go on a safari ($): y
Number of years since it opened in 2005: x
y=3.648*1.182^x
Cost in year 2013: y=?
Year 2013→x=2013-2005→x=8
y=3.648*1.182^8
y=3.648*3.810130162
y=13.89935483
y=13.90
The best estimate for the cost of a vehicle to drive through the safari in 2013 is $13.90
