A cab ride cost $3.25 for the 1st half mile and .70 for each mile after. How far can you travel with $12.
What is C = 3.25 + .70 (D - 0.5)
C = cost in $; D = distance in miles
$12 = $3.25 + .70 - .35
9.1 = .7D solve for D
D= 13 miles for $12
Nicole charges a flat fee of $3 plus $5 per hour to babysit. How much money will she make if she babysits for 5 hours.
Create equation in slope -intercept form
y =mx + b
Y = total revenue (C)
m = hours of baby sitting (h)
b = flat fee ($3)
C =$5(5Hrs) + $3
C = $25 +3
C = $28

If 3x + 8x + 4x = 6x + 63, then what is 5x + 23
What is 3x + 8x + 4x = 5x + 23
15x = 6x +63
9x =63

Solve this problem using the quadratic formula
2x^2 - 14x + 24 = 0
X = -b +/- the square root of b^2 - 4ac / 2a
a = 2 b = -14. c = 24
X = -(-14) +/- square root of -14^2 - 4(2)(24)/ 2(2)
-(-14) +/- square root of 196-192/4
X= 14 +/- square root 4/4
X= 14+/- 2/4
X = 16/4 = 4 or X = 12/4 =3
