During an oil change, each car needs 4 1/2 quarts of oil.
Each 5-quart container of oil costs $14.99.
Before tax, how much will the oil cost Mr. Richards for both cars in a year?
A
$44.97
B
$80.94
C
$89.94
D
$107.93
why is this c
6 * 4.5 = 27 quarts per year
27/5 = 5.4 = 6 containers a year
6 * 14.99 = ?
To find the answer, we need to calculate the cost of oil for both cars in a year.
First, we need to determine the number of oil changes Mr. Richards will have in a year for both cars. Assuming each car needs an oil change every 3 months, that means there will be a total of 4 oil changes in a year for both cars (2 cars x 4 oil changes = 8 oil changes in total).
Next, we need to calculate the total amount of oil needed for these oil changes. Each car needs 4 1/2 quarts of oil per oil change, so for both cars, we need 4 1/2 quarts x 8 oil changes = 36 quarts of oil in total.
Now, we need to calculate the number of 5-quart containers of oil needed. Since each 5-quart container costs $14.99, we can divide the total number of quarts needed (36 quarts) by 5 to get the number of 5-quart containers needed. In this case, 36 quarts / 5 quarts = 7.2, which rounds up to 8 containers.
Finally, we can find the cost of the oil for both cars in a year by multiplying the number of 5-quart containers needed (8 containers) by the cost of each container ($14.99). This gives us 8 containers x $14.99/container = $119.92.
However, the question specifies that we need to find the cost before tax. So, if we assume there is no tax on the oil, the answer would be $119.92.
Therefore, the correct answer is not option C ($89.94), but rather option B ($80.94) which is the closest value to the actual cost before tax.
