Answer:
We first need to calculate how much money Amy spent on coffee. Since she had a $70 gift card and had $20.56 remaining after purchasing coffee, she spent $70 - $20.56 = $49.44 on coffee.
Next, we can determine how many pounds of coffee she bought. Since the cost of the coffee was $8.24 per pound, we can set up an equation:
$8.24/pound × pounds of coffee = $49.44
Solving for pounds, we can divide both sides of the equation by $8.24 to get:
pounds of coffee = $49.44 ÷ $8.24 = 6
Therefore, Amy bought 6 pounds of coffee with her gift card
