The hospital daily rate is $615 this rate includes all hospital services with the exception of blood but which the hospital charges an additional $10 per pint if a patient was charge for 12 days of hospitalization and the total hospital bill
including blood was $8010 how many pints of blood to the patient receive?
a: 5
b: 6
c: 7
d: 8
pls explain

A. 5

Step-by-step explanation:

Given,

The daily rate of hospital services = $ 615,

Also, there is an additional charge of $ 10 per pint,

If x be the number of pints in each day,

Then the daily additional charges for x pints = 10x dollars,

So, the total daily charges = 615 + 10x

∴ The total charges for 12 days = 12(615 + 10x)

According to the question,

12(615 + 10x) = 8010

615 + 10x = 667.5

10x = 52.5

x = 5.25 ≈ 5

Hence, the patient receive approximately 5 pint daily.

Option 'A' is correct.

Step-by-step explanation:

A measure of variability is a summary statistic that represents the amount of dispersion in a dataset. How spread out are the values? While a measure of central tendency describes the typical value, measures of variability define how far away the data points tend to fall from the center. We talk about variability in the context of a distribution of values. A low dispersion indicates that the data points tend to be clustered tightly around the center. High dispersion signifies that they tend to fall further away.
