step 2: round $4.75 up to $5.00.
step 3: multiply 5 by 7 to get 35.
step 4: conclude that the cost will be just over $35.00.
in which step does eoin make a mistake?
a. in step 1, he should have rounded the weight down to 6 pounds.

Option (D) is correct .

Step-by-step explanation:

In the first step  
Eoin rounded up the 6.50 pounds of cheese to 7 .

Option (D) is correct .

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
