Answer: 1012.50
Step-by-step explanation:
The formula for calculating Simple interest is:
= Principal × Rate × Time
= 4500 × 7 1/2% × 3
= 4500 × 7.5/100 × 3
= 4500 × 0.075 × 3
= 1012.50
Therefore, the simple interest is 1012.50
Answer:
get y by itself and simplify
y=3/2x +7
Answer:
15000
Step-by-step explanation:
draw diagonal and make 2 traignles solve for the area of each one add them together
We can write a system of equations.
x + y = 77
y = x + 5
Plug in x + 5 into the first equation:
x + y = 77
x + (x + 5) = 77
So this is our answer.
Answer:
12.5%
Step-by-step explanation:
The price increased from 800 to 900. So what is the PERCENTAGE INCREASE??
The increase is 900 - 800 = 100
To find this in terms of original, we need to divide 100 by 800 and multiply by 100 to get the "percentage". Let's do it:

So the increase is 12.5% and thus the general sales tax is 12.5%
