Substitute the value 350 in for your velocity:
350 = 20 * sq rt(273+t)
divide both by 20 --> 17.5 = sq rt(273 +t)
square both to cancel out the sq rt --> 306.25 = 273 +t
then just subtract 273 from both to get 33.25 = t
Answer:
We conclude that the 8 % of calls result in a sale.
We conclude that the 5.3% of sales are made to women.
Step-by-step explanation:
We know that 70% of calls arc not completed (the party does not answer or refuses to talk), that 20% result in talking to a woman, and that 10% result in talking to a man. After that point, 30% of the women and 20% of the men actually buy something.
We calculate what percentage of calls result in a sale, and we get:

We conclude that the 8 % of calls result in a sale.
We know that the ratio of women to men talking on the telephone is 2:1.
We calculate a percent of sales are made to women, and we get:
