You're planning to buy a boat, a motor, and some miscellaneous boating equipment. the boat costs
$325, the motor costs $225, and the equipment costs $79. if you've saved $438 toward these purchases,
how much more do you need to save?

To calculate the amount you still need to save, we should know the total amount you need to be able to buy the things and subtract the amount you have currently to the total.

Total = $325 + $225 + $79 = $629
Amount needed to saved = $629 - $438 = $191

Therefore, you need to save $191 more.
