11 widgets are produced if the cost is $544.50
Explanation:
The cost C (in dollars) of producing x widgets is represented by C = 4.5

Given the cost = $544.50
C = 4.5
to find the value of x, substitute the value of C in the equation,
C = 4.5

544.5 = 4.5

121 =

x = 11
11 widgets are produced if the cost is $544.50
