Question

a tune up automotive facility marks up its parts by 45%. suppose that the facility charges its customers 2.32 for each spark plug it sells. what is the facilities cost for each spark plug?

Answer 1

Answer:

$1.6

Step-by-step explanation:

The price of $2.32 already includes the 45% mark up hence taking the original cost to be x, it means the cost of $2.32 is 145% of the original cost

Using the concept of cross multiplication we say that if

1.45 is equivalent to $2.32

1 is equivalent to x

$x=\frac {2.32}{1.45}=1.6$

Therefore, the company incurs $1.6 for each plug
