A furniture store pays a wholesale price for a mattress. Then, the store marks up the retail price to 150% of the wholesale pric

slega [8]

Part A:

Given that the mattress is sold for 50% off of the retail price, let the retail price of the mattress be x, then

50% of x = 1200
⇒ 0.5x = 1200
⇒ x = 1200 / 0.5 = 2400

Therefore, the retail price of the mattress, before the discount is $2,400.

Part B:

Given that the store marks up the retail price to 150% of the wholesale price. Let the whole sale price be p, then

(100% + 150%) of p = 2400
250% of p = 2400
2.5p = 2400
p = 2400 / 2.5 = 960.

Therefore, the wholesale price, before the markup was $960

3. A researcher studied the eyesight of people at different ages. She calculated a vision score for each person in the study and

WITCHER [35]

Answer:

A)Predicted value = 103.5

B)Actual value = 102

C)So, these are not same

Step-by-step explanation:

The researcher used the line $y = -0.1 x +110$ to model the data.

A)When the researcher substituted the value of x = 65 into this equation, what is the resulting y value?

Substitute value x=65 in equation :

y = -0.1 x +110

y=-0.1(65)+110

y=103.5

Predicted value = 103.5

B)Based on the coordinates of the given data points, what is the actual actual vision score when x=65?

Use the given graph

When x = 65

y = 102

So, The actual actual vision score when x=65 is 102

C)When the researcher substituted x = 65 into the line of equation, is the resulting y value the predicted value or the exit value for the vision score of a 65-year-old? Use your results for parts a and b to answer this question.

Predicted value = 103.5

Actual value = 102

So, these are not same
