Marcus and his twin sister Marcie decide to save $25 each week to buy a video console. How long will it take for them to save $675?
x= _
It will take Marcus and Marcie x weeks to save $675.
Since they save $25 each week, the amount they save in x weeks is 25x.
Setting up an equation, we have:
25x = 675
Dividing both sides by 25:
x = 27
Therefore, it will take Marcus and Marcie 27 weeks to save $675.
