Ответ:
x is the possible amounts she will spend
x > $54
Step-by-step explanation:
1. more than 9 pounds will be < 9
2. Since it is $6 per pound, then you will multiply 6 by 9, to find the least amount of money she will spend.
6 x 9 = 54
3. So she will at least spend $54.
4. Since it says that she will buy more than 9 pounds, so I would say that she will spend more than $54.
