Marcus and his twin sister Marcie decide to save $25 each week to buy a video console. How long will it take them to save $675

Marcus and Marcie are saving a total of $50 per week ($25 each).

To calculate how many weeks it will take them to save $675, we use the following equation:

$675 / $50 per week = 13.5 weeks

Since they can't save a fraction of a week, we round up to the nearest whole number.

It will take Marcus and Marcie 14 weeks to save $675.
