Question

Matt thinks that if Julie starts with $2, she will have $12 after 6 days. Explain what Matt is doing wrong.

Answer 1

Julie will have $12 on the 6th day not after the 6th day.

Step-by-step explanation:

Given

Day 1: $6

Required

Matt's error

First, I'll assume that Julie keeps $2 everyday.

So on the 6th day, the amount Julie will have is calculated as follows.

Amount = 6 * $2

Amount = $12

Hence, Julie will have $12 on the 6th day, not after the 6th day as Matt implies and this is what Matt is doing wrong.
