The interest Ernesto will earn in 1 year to the nearest cent is 2200 cents.
<u>Given the following data:</u>
To calculate how much interest Ernesto will earn in 1 year to the nearest cent:
<h3>How to calculate
compound interest.</h3>
Mathematically, compound interest is given by this formula:
<u>Where:</u>
- P is the principal or starting amount.
- T is the time measured in years.
Substituting the given parameters into the formula, we have;
B = $22.
<u>To cents:</u>
B = 
B = 2200 cents.

x= 9
y= 9
4x -2y= 18.................equation 1
-4x + 2y= -18...............equation 2
From equation 1
4x= 18 + 2y
x= 18 + 2y/4
substitute 18+2y/4 for x in equation 2
-4(18+2y/4) -2y= 18
-(18+2y)-2y= 18
-18-2y-2y= 18
-18+4y= 18
4y= 18+18
4y= 36
y= 36/4
y= 9
Substitute 9 for y in equation 1
4x-2y= 18
4x-2(9)= 18
4x-18= 18
4x= 18+18
4x= 36
x= 36/4
x= 9
Hence the value of x is 9 and the value of y is 9

15 * 15 * 15 * 500 = 1,687,500. it's different from finding 45 * 500 because
15 * 15* 15 * 500 is the same as writing it as 15^3 * 500. This meaning you multiply the number 15 by itself 3 times, not add it 3 times, which is what
45 * 500 was showing. I hope this helped.
90°
all angles of a triangle add up to 180°, so 45+45=90°, 180-90=90°, 90+90=180°
