Original Salary: 
Increase in 3%: 
Step-by-step explanation:
So when something increases by x%, the new value is (100+x)% the original value. So 6255, is 105% the original value. This means to find the original value, we have to find the number that has 6255 as 105% of it's value. Whenever you try to find x% of a number, you multiply it by the decimal value of the percentage, which is found by dividing by 100. So to find x%, you do: 
where o = original value, x=percent. In this case the percent is 105%, which when divided by 100 is 1.05. So this gives us the equation: 
. This is his original salary. You need to do this process, do not make the mistake of subtracting 5% from 6255. This is because 5% of 6255 does not equal the 5% of the original value. 5% of 6255 should be greater than 5% of the original value, since the new value is an increase of 5%. So since we have his original salary, we can calculate the salary increase had it been 3%. to do this we multiply by 1.03 (103% divided by 100). This gives us the equation: 
Answer:
Step-by-step explanation:
The distance that you travelled in your hummer between Olympia and Spokane is 319.4 miles.
You fill up your gas tank with 28.68 gallons of premium gasoline that costs $2.89 per gallon. This means that the total cost of premium gasoline that you bought would be
2.89 × 28.68 = $82.8852
your gas mileage in miles per gallon is 319.4/28.68 = 11.14 miles per gallon.
Therefore, if it costs $82.8852 to drive 319.4 miles,
then the cost of just one mile in your hummer would be
82.8852/319.4 = $0.26 per mile.
Answer:
x = 75°
Step-by-step explanation:
Sum of the interior angles of a triangle = 180°
Therefore,
78° + 27° + x° = 180°
Add like terms
105 + x = 180
105 + x - 105 = 180 - 105 (substraction property of equality)
x = 75°
