Suppose you receive an allowance of $55 and your friend receives an allowance of $40 at the beginning of the month. If you spend
$6 a day and your friend spends $3 a day, after how many days will you and your friend have the same amount of money?
1 answer:
Answer: 5 days
Step-by-step explanation:
so we need to find:
55 - 6a = 40 - 3a
with a being the days we need to find
-40 on each side
15 - 6a = -3a
+6a on each side
15 = 3a
divide each side by 3
5 = a
