How much was the initial fee for Jimmy's gym membership?
uhh $70?
We'll come back to that. How much was Jimmy's monthly membership fee?
idk it doesnt say
"Both gyms charge a one-time initiation fee plus a set cost per month."
It does say. You have to use context clues
$10
set cost per month
How much is the difference in cost from month two to month three for Jimmy?
$10?
Ah I see. Maybe it is $10
They skipped boxes for some months.
2 - 80 3 - 90 4 - 100 5 - 110
Good
Okay, so you know the initial fee and the cost per month so how can we write an equation to represent Jimmy's monthly cost?
y = 10x + 70 ?
Yes. Now we have to do the same for the other guy
ok
y = 15x + 50
Okay, so you should be able to set both expressions equal and solve for x
x representing the month both are paying the same amount
10x + 70 = 15x + 50 ?
Looks good
One sec, i always struggle at this part
How, why?
I know I'm supposed to get X on one said but
I know I'm supposed to get X on one said but
Do i start out with Dividing either 10x or 15x?
side*^^
You're supposed to subtract the like terms first
Oh really
I thought first, you get rid of one of the x's.
subtract and see what happens
do i subtract it from the variables too?
Yes
So i subtracted 50 and got -40x+20=-35x
Yeah you did that all wrong. Subtract the smaller numbers from the bigger numbers
What you should have done: 70 - 50 = 15x - 10x
50 is smaller than 70
50 is smaller than 70
You're a genius.
I didnt put the x's all on one side
You should do it the exact way I've shown.
70 - 50 is subtracting the smaller from the bigger BTW
50 is the smaller number being subtracted from the bigger number 70, thus 70 - 50
yeah i know
Problem was, i thought i would get rid of one of the X's so i didnt put constants w/ constants or variable w/ variables
like this, here's an example
you end up with 20 = 5x
Then divide both sides by 5
4= x
um
We can check that to make sure
See if both month 4 values are the same
Clearly not
@Vocaloid
I was going with the values you created yourself. If they are not right then the next step is to go back and make sure they are all correct.
No, my values are just fine, your answer is just wrong
Jimmy Gymboree 1= 70 1= 35 2= 80 2= 50 3= 90 3= 65 4= 100 4= 80 5= 110 5= 95 6= 120 6= 110 7= 130 7= 125 8= 140 8= 140
They meet on month 8
1st, it's not my value, it's your value based on your equations you came up with.
2nd, you need to go back and make sure the values for initial fee and monthly fee are correct
Yeah that's what I'm doing, the initial fee for Gymboree is 35 not 50
Okay
Weird, i still end up with 7 and not 8
10x + 70 = 15x + 35 70-35 = (15 - 10)x 35 = 5x 35/5 = 7 = x yep so something is still off.
I re-checked my table, it looks correct to me
How do you figure?
For Jimmy i added 10 and other guy is 15
