Allison has $100 in her lunch account. She spends $6 for lunch each day. Amirah has $160 in her lunch account. She spends $10 each day. After how many day will the girls have the same amount of money in their accounts?

15 days

Step-by-step explanation:

So first we know that Amirah spends more money than Allison each day however, Allison has only 100 to 160. So first I would multiply it by 6 days so you would reduce 30 dollars from Allison's account then you reduce 60 dollars from Amirah's account. This would make it 70 and 100. Then we add another 3 days which would make them 52 and 70. Then we would add 2 more than we would have 40 and 50. Then add 4 more days. 10 and 10.

6+3+2+4=15

Henceforth, your answer would be 15 days.
