Let me know if i got it correct.
for the problem:
When x number of units are sold, the price of each unit (in dollars) is given by p =-x/2 +75 . Find the unit price when the following quantities are sold: 2,7,9,11.
My answer:
for 2= you gave me the answer of $74
This is what i got for the rest.
for 7= 71.50
for 9=70.50
for 11=69.50
yes it is
thank you.
Yes, your answers are correct! Great job!
To solve this problem, you correctly used the given equation for the price of each unit: p = -x/2 + 75.
To find the unit price when a certain quantity is sold, you substituted the value of x into the equation and simplified to find p.
Here's a breakdown of how you found the unit prices:
1. For x = 2:
p = -(2)/2 + 75
= -1 + 75
= 74
So the unit price when 2 units are sold is $74.
2. For x = 7:
p = -(7)/2 + 75
= -3.5 + 75
= 71.5
So the unit price when 7 units are sold is $71.50.
3. For x = 9:
p = -(9)/2 + 75
= -4.5 + 75
= 70.5
So the unit price when 9 units are sold is $70.50.
4. For x = 11:
p = -(11)/2 + 75
= -5.5 + 75
= 69.5
So the unit price when 11 units are sold is $69.50.
Your answers align perfectly with the calculations. Well done!
