Answer:
a. 16
b. 80
c. Blood type AB
Step-by-step explanation:
Given:
O = 45%
A = 40%
B = 11%
AB = 4%
Total number of donors = 145
a. No. of donors that had type B blood = 
Type B blood donors ≈ 16
b. No. of blood donors without blood type O = 
Those without blood type O ≈ 80
c. Find the number of people that had type AB:
Type AB = 
≈ 6. This is less than 10 donors.
Therefore, blood type AB had less than 10 donors.
Given :
Weekly salary , S = $150.
Commission per car , C = $325.
To Find :
The the equation that models the weekly salary of a car salesman.
Solution :
We know it is a quadratic equation :
Let , the equation is , y = mx + c
Here, x is number of car sold in a week.
For x = 0 ( He will not get commission)
So , Salary is $150 = c .
For x = 1
Salary is $( 150 + 325 ) = $475 = m(1) + c
Therefore , m = $325 and c = $150.
Required linear equation is y = 325x + 150.
Hence, this is the required solution.
The price elasticity of demand of the pen will be -0.2.
<h3>How to compute the elasticity?</h3>
The demand and supply schedule will be:
Price Qd. Qs
$10. 250. 100
$20. 200. 90
$30. 180. 80
The price elasticity of demand from $1 to $2 will be:
= Percentage change in quantity demanded/percentage change in price
Percentage change in quantity demanded will be:
= (200 - 250)/250 × 100
= -20%
Percentage change in price will be:
= (20 - 10)/10 × 100
= 100%
Therefore, the elasticity of demand will be:
= -20/100
= - 0.2
The value gotten illustrates an inelastic demand.
In order to increase the total revenue, the price can be reduced as it will lead to more sales.

There are 8 pints in a gallon. It will take 10 days to drink 1 5-gallon container.
30 / 10 = 3
He will drink 3 containers. Hope this helped :)
