Award brainliest if helped pls!
Assuming a linear relation,
let X be number of units and Y be total cost
Y=mX+C
22000 = 4000m +C
and
30000 = 6000m+C
Solving the equations simultaneously, m= 4 , C= 6000
To solve when X = 4500,
Y=4X+6000
Y=4(4500)+6000 =24000
The total cost is 24000 when 4500 units are produced.
