# If the total cost of producing 1500 items at $3 each is$4860, how do you find the cost equation?

May 29, 2018

The cost equation in $ is $y = 3 n + 360$#### Explanation: Let x=$3 is the cost of $1$ item and number of item be $n$

and other cost is $c$(constant) for all items, and total cost

be $y for $n$items , then $y = n \cdot x + c$$y = 4860 , x = 3 , n = 1500 \therefore 4860 = 1500 \cdot 3 + c$or  c= 4860 -4500 or c =$360 Therefore the cost equation

becomes $y = n x + 360 \mathmr{and} y = 3 n + 360$.

The cost equation in $ is $y = 3 n + 360\$.[Ans]
