Maria rented a minivan for $54 per day for 8 days and drove 1452 miles .she was allowed 150 free miles ,and was charged 25 cents for each additional miles . what was the total rental cost

54×8=432 1452-150=1302×.25=325.50+432.00=757.50

Step-by-step explanation:

54•8=$432.00
She drove for 8 days and she had to pay $54.00 a day so you multiply.

1452-150=1302 miles
She drove 1452 miles and she got 150 free miles so you subtract to find the amount of miles you need to pay.

1302•.25=$325.5
She had to pay for 1302 miles and each mile is .25 cents so to get the money she had to pay you multiply.

432.00+325.50=$757.5
Add up the total to get your answer

$747.50 was the total rental cost.

The expected number of people who will attend the concert is 8500 and this can be determined by using the given data.

Given :

For an outdoor concert by the city orchestra, concert organizers estimate that 10,000 people will attend if it's not raining.If it is raining, concert organizers estimate 5000 people will attend. On the day of the concert, meteorologists predict a 30% chance of rain.

Given that the probability of having rain is 30% that is 0.3.

So, the probability of not having rain is 1 - 0.3 = 0.7.

Now, the expected number of people who will attend the concert will be:

= (probability of not having rain number of expected guests when it does not rain) + (probability of the raining number of expected guests when rains)

= 1500 + 7000

= 8500

So, the expected number of people who will attend the concert is 8500.
