Question

Xander has $15 and make $4 a day. Aislyn has $10 and makes $4 a day. When will they have the same amount of money?

Answer 1

Answer: Never because Aislyn cannot catch up if they make the same amount of money per day.

Step-by-step explanation:

Assume that the day they will have the same amount of money is x.

The amount that Xander will have on that day is:

= 15 + 4x

The amount that Aislyn will have on that day is:

= 10 + 4x

Equate the two fractions:

15 + 4x = 10 + 4x

15 - 10 + 4x = 4x

5 = 4x - 4x

5 = 0x

What this means is that they will never have the same amount of money because they are increasing by the same amount so Aislyn will never catch up.
