You will need to set up your table of values for each person.
Let x represent the months, and y for the amount of money.
For Carissa: For Louann:
x = y x = y
-- -- -- --
0 $250 0 $1230
1 $330 1 $1170
2 $410 2 $1110
3 $490 3 $1050
4 $570 4 $990
5 $650 5 $930
6 $730 6 $870
7 $810 7 $810
You could also do the equation:
80x + 250 = -60x + 1250
where you will get x=7.
Then substitute 7 to the x's in the equation which will give you $810 for each.
The answer is: It will take 7 months. Then, they will both have $810 in their accounts.
Answer:
The cost of soft pretzel is $1.25
Step-by-step explanation:
Let $x be the price of one slice of pizza and $y be the price of one soft pretzel.
1. 9 slices of pizza cost $9x and 5 soft pretzels cost $5y. Together they cost $33.25, then
9x+5y=33.25.
2. 4 slices of pizza cost $4x and 6 soft pretzels cost $6y. Together they cost $19.50, then
4x+6y=19.50.
3. Solve the system of two equations:

Multiplythe first equation by 4, the second equation by 9 and subtract them:

Then

Assuming the envelope consumption is proportional to the number of typists, you have ...
(12 dz)/36 = x/125
125*(12 dz)/36 = x = 41 2/3
An office of 125 typists would use 41 2/3 dozen envelopes per day.
