a.
To find:The prices for an oil change, a radiator flush, and a brake pad replacement.
a.

Answer to Problem 22PPS
The price for an oil change is $19.99, for a radiator flush is $10, for a brake pad replacement is $20.
Explanation of Solution
Given information:
Ramon usually gets one of the routine maintenance options at Annie’s Garage. Today, however, he needs a different combination of work than what is listed. It is assumes that the price of an option is the same as purchasing each item separately.
Calculation:
Let the price for an oil change be x ,
The price for a radiator flush be y ,
The price for a brake pad replacement isz .
The price for oil change and radiator flush is $29.99
Then,
The price for brake pads and oil change is $ 39.99
Then,
The price for oil change, radiator flush and brake pads is $49.99
Then,
Subtracting equation (1) from (3),
Subtracting equation (2) from (3),
Substituting
Thus, the price for an oil change is $19.99, for a radiator flush is $10, for a brake pad replacement is $20.
b.
To find: The price for brake pads replacement and radiator flush.
b.

Answer to Problem 22PPS
$30
Explanation of Solution
Given information:
Ramon usually gets one of the routine maintenance options at Annie’s Garage. Today, however, he needs a different combination of work than what is listed. It is assumes that the price of an option is the same as purchasing each item separately.
Calculation:
The price for brake pad replacement is $20 and that of radiator flush is $10.
Then, total cost
Thus, Ramon should spend $30 for brake pad replacement and radiator flush.

They are playing a game where they randomly pick a card out of the hat four times, with replacement. Amy thinks that the probability of getting exactly two aces in four picks is equal to the probability of not getting exactly two aces in four picks. Samiha disagrees. She thinks that the probability of not getting exactly two aces is greater. The sample space of possible outcomes is listed below. A represents an ace, and K represents a king.
