The linear model for the data is expressed as: R = 20p - 160.
<h3>How to Write a Linear Model?</h3>
Using two pairs of values from the table values, say, (32, 480) and (33, 500), find the unit rate (m).
Unit rate (m) = (500 - 480)/(33 - 32) = 20/1
Unit rate (m) = 20.
Substitute (p, R) = (32, 480) and m = 20 into R = mp + b to find b
480 = 20(32) + b
480 = 640 + b
480 - 640 = b
b = -160
To write the linear model, substitute m = 20 and b = -160 into R = mp + b:
R = 20p - 160

Answer:
-4.85714285714
Step-by-step explanation:
You do 15/4 MULTIPLIED by 2/5 (you change the division sign to a multiplication sign) then you multiply the fractions : 15*2=30 and 4*5=20 so it would equal to 30/20 which can be halved to give 15/10
