Answer:
Mary removed the dollar sign from (X.)
We know this because $4.00x$5.00=$20.00 so that’s correct and we know that $12.50x $4.00=$50.00. So, our only error here is that there is no dollar sign in our (X) numbers. So that is Mary’s mistake. We can correct it by simply adding a dollar sign to 20 to make $20.00 and adding another dollar sign to 50 to make $50.00

Answer:
Their savings will be same after 25 weeks.
Step-by-step explanation:
The difference in both person's saving is $ 2/week
$5-$3=$2
The total difference in the starting point is $50 if we divide $50 by $2 we will get a number of 25 which is the number of weeks it will take both savings to reach at a same level
Calculation:
Starting point $150
Savings $5/week
5*25+150= $275
Starting point: $200
Savings 3$/week
3*25+200= $275
