ANSWER : Rozalie spent 6.73 hours at the garage
rate of change = $2.75
base fee = $7.50
set up your equation:
2.75h + 7.5 = 26
($2.75/hour plus the base fee of $7.50 equals the total amount spent, $26)
Now just solve for h
2.75h + 7.5 = 26
2.75h = 18.5
h = 6.727273 (rounded)
h = 6.73
So the answer would be Rozalie spent about 6.73 hours at the garage.
No it is not base e. It is 1.015.
An increase of 1.5 % = 1.015
Year 1, 2, 3,.........................., 30.
30000, 3000(1.015), 30000(1.015)²,........... 30000(1.015)²⁹
Her Total Income is sum over the thirty 30 year period:
Sn = a(r^n - 1) / (r - 1); a = 30000, r = 1.015, n = 30
Sn = 30000 ( 1.015^30 - 1) / (1.015 - 1)
= 30000 (1.56308022 - 1) / (0.015) = 1126160.44
Total = $ 1 126 160.44
3/4*8= 24/4= 6 this is 3/4 the distance between point a and b
