Amount of car loan taken by Scott = $5500
Amount of loan paid back by Scott = $7370
Then
Amount of money paid as interest by Scott = (7370 - 5500) dollars
= 1870 dollars
Then
Percentage of interest given for the car loan = (1870/5500) * 100
= 1870/55
= 34 percent
So Scott had to pay a total interest rate of 34% in the four years.I hope the procedure is simple enough for you to understand and solve future problems.
First you find 4/5 of 8 and then 4/5of 7 and multiply them
Answer:
(a) The constant of proportionality is 0.25
(b) 1 apple = $0.25
(c) $3 = 12 apples
Step-by-step explanation:
Given
Solving (a): The constant of proportionality;
For an equation:
Where
k = constant of proportionality
By comparing: to
Hence, the constant of proportionality is 0.25
Solving (b): What information does gives.
It represents the unit rate.
<em>So, it means that 1 apple costs $0.25</em>
<em></em>
Solving (c): Number of apples for $3.
This means that 
Substitute 3 for c in
Make n the subject
Your answer is y = 3x + 24.
We already know that the first part of the equation is 3x, as the slope has been given to us. This means all we have to figure or is the y-intercept, which we can do by substituting in the coordinates we were given:
y = 3x + c
-7 = (3 × -8) + c
-7 = -24 + c
+ 24
17 = c
This gives us our y-intercept as 17, so then the final answer is y = 3x + 17.
I hope this helps!

Multiplicative Identity states that any time you multiply a number by 1, the result is the original number.
