Solve the problem.
-The profit made when $t$ units are sold, $t0$, is given by $P=t^{2}-22 t+120$. Determine the number of units to be sold in order for $\mathrm{P}=0$ (the break- even point).
A) $t=-12$ or $t=-10$
B) $t=12$ or $t=10$
C) $t12$
D) $t=22$

Question

Solve the problem.
-The profit made when $t$ units are sold, $t>0$, is given by $P=t^{2}-22 t+120$. Determine the number of units to be sold in order for $\mathrm{P}=0$ (the break- even point).
A) $t=-12$ or $t=-10$
B) $t=12$ or $t=10$
C) $t>12$
D) $t=22$

Quizplus · Accepted Answer

To find the break-even point, set $P=0$ and solve for $t$:$$0=t^{2}-22 t+120$$$$0=(t-10)(t-12)$$Therefore, the break-even points are $t=10$ and $t=12$.
