Lets represent Ana and Christion using the Letters A and C
a+c=500
c=a+150
now substitute c for a+150 back into the first equation
a+a+150=500
a+a=350
2a=350
Divide by two
a=175
Now that we know annie has 175 all we do is subtract that from the total (500)
C=325
Sure enough, 175 is 150 less than 325
Hope that helped, send me a message if you need clearing up :D

SOMEBODY PLZ HELP FAST!!! Use the data in the stem-and-leaf plot to match the term in Column A to the answer in Column B.
irakobra [83]
12, 13, 15, 20, 24, 25, 26, 31, 33, 34

First, let's just find everything (minimum, maximum, Q₁, median {Q₂}, Q₃)

Minimum : 12, because it is the lowest number.

Maximum : 34, because it is the highest number.

Median (Q₂) : 24.5, because it is the middle number.

Q₁ : 15, because it is between 24.5 and 34

Q₃ : 31

So,

1)  d-12

2)  c - 34

3)  b-15

4)  f-24.5

5)  a-31

you are choosing betweem two health clubs. Club A offers membership for a fee of $23 plus a monthly fee of $18. Club B offers me
Lady_Fox [76]
What we could do first is for club A we can add up $23 + $18 which = $40. so the cost would for club A would be $40.

Now club B. Club B charges $14 + 19 that would = $33. so monthly it would be $33

But if you were looking how much money you would spend in 1 year you would have to multiply for club A 40 x 12 which is 480$

and the yearly cost for club B you would have to multiply 33$ times 12 which is $369 per year
