The cost C (in dollars) of producing x widgets is represented by C = 4.5x squared. How many widgets are produced if the cost is $544.50

Step-by-step 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

step-by-step explanation:

(s)he  is right it would be 5.5% because it is smaller than 15.5% or anything smaller than 15.5% in general
