Question

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

Answer 1

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
`x^(2)`

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
`x^(2)`

544.5 = 4.5
`x^(2)`

121 =
`x^(2)`

x = 11

11 widgets are produced if the cost is $544.50
