Quick Computing's cost function will take
the form of a quadratic function
c(x) = ax² + bx + c
where a, b, and c are constants, a*0,
and x is the number of calculators produced.
Recall the following conditions given in
the problem:
• It costs $50 to make 10 calculators.
• It costs $100 to make 20 calculators.
.
• It costs $250 to make 30 calculators.
We will represent this information with
three equations. They will be used to find
the values for a, b, and c.
Let's set up the first equation by finding x.
Find the number of calculators, x, when the
cost, c(x), is $50.
Enter the correct answer.
