Question

5. Kristin and Louis had the same amount of biscuits at
first. Each day, Kristin ate 4 biscuits while Louis ate
6 biscuits. When Louis had 4 biscuits left, Kristin had
4 times as many biscuits as him. How many biscuits did
Kristin have at first?​

Answer 1

Answer:

10

Step-by-step explanation:

Example 100 biscuits each of them: Kristin and Louis each had 100 biscuits at first (Sunday). Then each day Kristin ate 4 while Louis ate 6. Kristin: 100 minus 4 each day from Monday to Friday is equal to 80 or 100-4-4-4-4-4=80. Louis: 100 minus 6 each day from Monday to Friday is equal to 70 or 100-6-6-6-6-6=70.

80-70= 10
