Answer:
5 pounds
Step-by-step explanation:
Given that:
Amount of gift card = $80
Cost of coffee per pound = $8.24
Amount left in the card = $38.80
To find:
Number of pounds of coffee bought = ?
Solution:
Let the number of pounds of the coffee bought = [tex]x[/tex] pounds
Cost of 1 pound = $8.24
Cost of [tex]x[/tex] pounds = $8.24 [tex]\times x[/tex]
Writing the equation as per question statement:
[tex]80 - 8.24x = 38.80\\\Rightarrow 80 - 38.80 = 8.24x\\\Rightarrow 8.24x = 41.2\\\Rightarrow x = \dfrac{41.2}{8.24}\\\Rightarrow \bold{x = 5\ pounds}[/tex]
Therefore, 5 pounds of coffee was bought.
