Answer:

≈ 44.4%%%

Step-by-step explanation:

The person will wait for no more than 20 minutes if they arrive when the bus is going to stop in 20 minutes, which means that they must arrive 25 minutes after the previous bus stops. So the probability that the person will not wait for more than 20 minutes will be \frac{20}{45} which is about 44.4%.

Danielle earned $969 last week if she sold $4,400 in electronics merchandise

<h3><u><em>Solution:</em></u></h3>

Given that, Danielle earns a 7.25% commission on everything she sells at the electronics store where she works.  

She also earns a base salary of $650 per week.  

We have to find how much did she earn last week if she sold $4,400 in electronics merchandise?  

Now, we know that, earned amount = base salary + commission

Given that she earns a 7.25% commission on everything she sells

<em><u>So commission earned for selling $ 4400 is given as:</u></em>

commission earned = 7.25 % of 4400

\text { commission earned }=\frac{7.25}{100} \times 4400=7.25 \times 44=319

Earned amount = base salary + commission = 650 + 319 = 969

Hence, she earned $969 last week
