Answer: Jina bought 5 pounds of coffee by spending a total of $38.60.
Explanation:
According to this problem, Jina has an $80 gift card for a coffee store and when she bought some pounds of coffee, she had $41.40 left.
To solve this equation you will need to rephrase this equation to
80 - 41.40 = x
When you subtract the problem, you should get $38.60.
80 - 41.40 = 38.60
Now since Jina bough coffee that costs $7.72 per pound, you will need to divide that by the amount you have just subtracted.
38.60 ÷ 7.72
When you divide "38.60 ÷ 7.72", you should get the number 5.
Therefore, Jina bought 5 pounds worth of coffee, making her total on her gift card $38.60. Hope this helps!
