Answer: The predictor variable in this problem is the amount spent on promotional material.
Explanation:
A predictor variable refers to variable needed to make a prediction of another variable. If we analyze the problem, we notice that the supermarket chain is predicting the sales revenue generated because once the supermarket spends on promotional material, it will result to sales revenue.

6 apartments in 2.5 hours
30 apartments in ? Hours
6/2.5=30/x
6x=(30)(2.5)
x=75/6
x=12.5 hours
Answer is 72
Step by step
Using order of math rules of PEMDAS, we do the inner parentheses “P” first, working outwards with parentheses and then exponents, multiply and divide, add and subtract.
2x [4x(2+1)x3] add inner parentheses
2 x [4 x 3 x 3] multiply inside brackets
2 x 36 multiply for your answer
= 72
