Answer 1

Answer:

4 pounds

Step-by-step explanation:

Do 70 - 39.56 = 30.44 To see how much she spent

Do 30.44 / 7.61 = 4 To see how many pounds of coffee she had bought

Answer 2

Answer:

4

Step-by-step explanation:

Amount spent on coffee = 70 - 39.56 = 30.44

One pound costs 7.61, how many will cost 30.44

7.61 : 1 = 30.44 : X

7.61 = 30.44/X

X = 30.44/7.61

X = 4
