The current salary is <span> $44,200. In this case, the percent increase is 4%. The percent increase serves like an investment in which the interest is compounded. The formula that applies here is current = previous *( 1.04)^n where n is 1. Last year's salary is $42,500</span>
Answer:
631139.04 kilometers in 3 years
Step-by-step explanation:
Let x = how many kilometers she walk
y = time (minutes)
Since she walks 4km in 10 minutes.
x = 4, y = 10
(4,10)
But how many minutes if she walk only a kilometer? Divide x and y by 4.
(1,2.5)
She walks a kilometer under 2.5 minutes.
Now finding rate of changes.
![\displaystyle \large{m = \frac{10 - 2.5}{4 - 1} } \\ \displaystyle \large{m = \frac{7.5}{3} } \\ \displaystyle \large{m = 2.5}](https://tex.z-dn.net/?f=%20%20%5Cdisplaystyle%20%5Clarge%7Bm%20%3D%20%20%5Cfrac%7B10%20-%202.5%7D%7B4%20-%201%7D%20%7D%20%5C%5C%20%20%5Cdisplaystyle%20%5Clarge%7Bm%20%3D%20%20%5Cfrac%7B7.5%7D%7B3%7D%20%7D%20%5C%5C%20%5Cdisplaystyle%20%5Clarge%7Bm%20%3D%20%202.5%7D)
Since m = 2.5
and of course, the function should be proportional so the equation should be y = mx.
![\displaystyle \large{y = 2.5x }](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Clarge%7By%20%3D%202.5x%20%7D)
Since time should be minutes instead of years.
Since 3 years = 1577847.6 minutes
![\displaystyle \large{1577847.6 = 2.5x}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Clarge%7B1577847.6%20%3D%202.5x%7D)
Divide both sides by 2.5
![\displaystyle \large{ \frac{1577847.6}{2.5} = x} \\ \displaystyle \large{631139.04 = x }](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Clarge%7B%20%5Cfrac%7B1577847.6%7D%7B2.5%7D%20%3D%20x%7D%20%5C%5C%20%5Cdisplaystyle%20%5Clarge%7B631139.04%20%3D%20x%20%7D)

6 buses with 32 students per bus.....6 x 32 = 192 students
each row seats 8 students...192/8 = 24 rows will be needed for all students
Answer:
x=17, y=9
Step-by-step explanation:
(5x - 38)° = (3x - 4)°
2x = 34
x=17
(5(17)-38))=47
90°+47°+(7y-20)=180°
7y-20=43°
y=9
