The cost of manufacturing clocks is given by $c=9(n+49)^{1 / 2}$, where $c$ is the cost in dollars and $n$ is the number produced. What is the cost when no clocks are produced?
A) $\$ 9$
B) $\$ 21$
C) $\$ 63$
D) $\$ 441$

When no clocks are produced, $n = 0$. Substituting $n = 0$ into the cost function $c = 9(n+49)^{1/2}$, we get $c = 9(0+49)^{1/2} = 9 \times 7 = 63$.

The Cost of Manufacturing Clocks Is Given By c=9(n+49)1/2c=9(n+49)^{1 / 2}c=9(n+49)1/2

The Cost of Manufacturing Clocks Is Given By $c=9(n+49)^{1 / 2}$
