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%
firstly, I'd like to point out the graph is misleading, if AC is 10 it should be the shorter sides, but it shows as the longer side there.
let's bear in mind that in a rhombus, all sides are equal, even though they may be slanted, the diagonals meet at right-angles always, so the center is simply four 90° angles, and the diagonals bisect each other, namely they cut each other in equal halves.
check the picture below.
a) Simple interest earned by customer in 10 years is $ 675
b) Account balance after 10 years is $ 5175
<em><u>Solution:</u></em>
<em><u>The simple interest is given by formula:</u></em>
Where,
"p" is the principal
"r" is the rate of interest
"n" is the number of years
<em><u>a. How much interest will the customer earn in 10 years?</u></em>
From given,
Principal = p = $ 4500
Simple interest rate = r =1.5 %
n = 10
Substituting the values in formula,
Thus simple interest earned by customer in 10 years is $ 675
<em><u>b. What will the account balance be after 10 years ?</u></em>
Account balance = principal + simple interest
Account balance = 4500 + 675 = 5175
Thus account balance after 10 years is $ 5175
