Answer: Brand A is cheaper per bag
Explanation:
First brand:
45 bags cost $8.99
A bag will cost $8.99/45 = $0.1998
Second brand:
32 bags cost $7.75
A bag will cost $7.75/32= $0.242
But a saving coupon of $0.25 for second brand
So $7.75-$0.25= $7.50
And $7.50/32 =$ 0.234
From the above calculation.. brand a is cheaper .
