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
[tex]x=\frac {2.32}{1.45}=1.6[/tex]
Therefore, the company incurs $1.6 for each plug
