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?

$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

Therefore, the company incurs $1.6 for each plug

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
