Write the Next three instances
9 · 4 + 9 · 1 = 9 · 5
9 · 4 + 9 · 2 = 9 · 6
9 · 4 + 9 · 3 = 9 · 7
9 · 4 + 9 · 4 = 9 · 8
9 · 4 + 9 · 5 = 9 · 9
9 · 4 + 9 · 6 = 9 · 10
9 · 4 + 9 · 7 = 9 · 11
Solve:
Five friends equally split a restaurant bill that comes to $32.50. How much does each friend pay?
Each friend pays $6.50.
WORK

You work for 4 hours on Saturday and 8 hours on Sunday. You receive a $50 bonus. You earn $164.00 total. How much did you earn per hour?
You earned $9.50 per hour.
WORK
4x + 8x + 50 = 164
12x + 50 = 164
12x + 50 - 50 = 164 - 50
12x = 114
12x/12 = 114/12
x = 9.5 ~~~> $9.50

Use a graphing calculator to calculate the mean,
These two data sets give the lengths of terms of Presidents of the United States and the reigns of kings and queens of England. Years served by the first 42 American presidents: 8, 4, 8, 8, 8, 4, 8, 4, 0, 4, 4, 1, 3, 4, 4, 4, 4, 8, 4, 1, 3, 4, 4, 4, 5, 7, 4, 8, 2, 6, 4, 12, 8, 8, 3, 5, 6, 2, 4, 8, 4, 8

Solve for p:
1.5p = 1.25p + 8
p = 32
WORK
1.5p = 1.25p + 8
1.5p - 1.25p = 1.25p - 1/25p + 8
0.25p/0.25 = 8/0.25
p = 32
Solve:
Two buildings have the same total height. One building has 8 floors with height, h. The other building has a ground floor of 16ft and 6 other floors with height, h. Write and solve an equation to find the height, h, of these floors.
8h = 16 + 6h
h = 8
WORK
8h = 16 + 6h
8h - 6h = 16 + 6h - 6h
2h = 16
2h/2 = 16/2
h = 8
In World War II, Germany was going to try and collapse the British economy by?
dropping millions of counterfeit bills over London.
Solve for x:
3.5 - 0.02x = 1.24
x = 113
WORK
3.5 - 0.02x = 1.24
100*(3.5 - 0.02x) = 1.24*100
350 - 2x = 124 [Distributive Property]
350 - 350 - 2x = 124 - 350
-2x/(-2) = -226/(-2)
x = 113
Suppose you begin the day at an elevation of E feet. After some hiking, you are at an elevation of H feet.
What is the absolute deviation of where you are now from where you began?
|H - E|
Solve for p:
-2.54 = p + 7.17
p = -9.71
WORK
-2.54 = p + 7.17
-2.54- 7.17 = p + 7.17- 7.17
p = -9.71

Solve for x:
9m - 4 = -3m + 5 + 12m
NO SOLUTION
-4 = 5
WORK
9m - 4 = -3m + 5 + 12m
9m - 4 = -3m + 12m + 5
9m -9m - 4 = 9m -9m + 5
-4 = 5 <~~~NO! So, No Solution!

Pristine Printing will print business cards for $0.10 each plus a setup charge of $15. The Printing Place offers business cards for $0.15 each with a setup charge of $10. What number of business cards costs the same from either printer? BONUS: What would the cost be?
Printing 100 cards would cost the same from either business.
WORK
0.10n + 15 = 0.15n + 10
0.10n - 0.10n + 15 = 0.15n - 0.10n +10
15 = 0.05n + 10
15 - 10 = 0.05n + 10 - 10
5 = 0.05n
5/0.05 = 0.05n/0.05
100 = n ~~~>100 cards
BONUS answer: It would cost $25.00 to make 100 cards from either place.
WORK
0.10n + 15 = ??
0.10(100) + 15 = 25 ~~~>$25.00
0.15n + 10 = ??
0.15(100) + 10 = 25 ~~~>$25.00
