Hello!
Let's solve this step by step!
So, we know that after Donna will have $30.80 remaining after buying a certain number of pounds, and we also know that each pound of coffee costs $7.84.
Subtract the amount that will be left from the gift card.
70 - 30.80 = 39.2
Now, divide this by the cost per pound.
39.2 ÷ 7.84 = 5
A N S W E R:
Donna bought 5 pounds of coffee.
Good day!
