Question

this is the word problem:

The mean of Mr. Moore's salary fo the past 3 years is $26,500. If he earned $23,000 his first year and $26,000 his second year, how much did he earn his third year?

i turned it into an equation:

26,500=(23,000+26,000+y)/3

is the equation correct? if it is, how do you solve it? plz help me by showing step-by-step. thanx

thank you, here's another one i can't figure out:

x-y=23.7
x+y=61.1

again, plz show me step-by-step

Answer 1

yes, your equation is correct.

26,500=(23,000+26,000+y)/3

now multiply by 3:

79500 = 23000 + 26000 + y

then subtract to get y on it's own

y = 30,500

And then you can check by adding the 3 salaries together and dividing by 3

23000 + 26000 + 30500 = 79500

79500/3 = 26500

Answer 2

Yeah that's right

26,500=(23,000+26,000+y)/3
Well add the terms in paranthensis first
so you get
26,500=(49,000+y)/3
Then multiply both sides by 3 to get
79500=49,000+y
then subtract 49,000 from 79500
to get 30500

Answer 3

26,500=(23,000+26,000+y)/3

Well, that's definitely correct. First, get rid of the three by multiplying both sides by it.

79500 = 23000 + 26000 + y

Simplify by adding the two numbers on the left side.

79500 = 49000 + y

And then solve for y by subtracting 49000 from both sides.

30500 = y

That should do it. ;D

He made $30,500 in his third year.

Answer 4

Y=30,500

26500=(23,000+26,000+30,500)/3

26500*3=23000+26000+y (multiply by 3 to cancel out)

79500=29000+y (Minus constants)

30,5000=y

26500=(23000+26000+(30500))/3

Answer 5

Yes, the equation is right. I think that this is how you solve it:
26,500=(23,000+26,000+y)/3
26,500=(49,000+y)/3
3(26,500)=(49,000+y)/3(3)
79,500=49,000+y
-49,000 -49,000
_______________
30,500= y
and that's your answer!!
I sure hope that this helped...and I sure hope that it's right!!
