How might technologically-advanced prosthetics have with clapp’s rehabilitation?

Rehabilitation ... a series of prosthetics, each more technologically advanced than the last, he has ... “I do have a lot of motivation and self-esteem,” Clapp says, “but I might look at myself differently if technology was not on my side.” Each of these examples of serendipity helped advance the scope of human knowledge by.

C=0.5x + 10

Where:
C = total cost of printing
x = number of business cards printed
0.5 = variable cost of printing, this cost depends on the number of business card
10 = fixed cost of printing, this cost stays the same regardless of the number of business card printed.

C = 0.5x + 10  ; derive the formula of x.

C - 10 = 0.5x

(C - 10)/0.5 = x
