Answer:
6.72<x<10.08
Step-by-step explanation:
multiply 1.12 and 6 for the low end
multiply 1.12 and 9 for the high end
Answer:
6.72<=X<=10.08
Step-by-step explanation:
6*1.12<=X<=9*1.12
We put 6*1.12 because that is the least she would pay, putting it into the lower end.
We put 9*1.12 because that is the most she would pay, putting it into the higher end.
6.72<=X<=10.08
