Answer: Kira bought 3 pounds of coffee
Explanations:
The price of giftcard that Kira received = $70
The amount of money Kira has left after buying the coffee = $46.78
The total price of coffee Kira bought = (The amount of giftcard she received) - (The amount of money she has left)
The total price of coffee Kira bought = $70 - $46.78
The total price of coffee Kira bought = $23.22
Cost of 1 pound of coffee = $7.74
Number of pounds of coffee bought =
(The total price of coffee Kira bought) / (Cost of 1 pound of coffee)
Number of pounds of coffee bought = $23.22 / $7.74
Number of pounds of coffee bought = 3 pounds
