Question

Sally and her friend Lucie started saving money for their vacation on the same day. Sally started with $150 and plans to add $5 to the total every week. Lucie started with $200 and plans to add $3 to the total every week. After how many weeks will their savings be the same?

Answer 1

Their savings will be same after 25 weeks.

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
