Question

Trent saved up to $500 for sale for summer vacation if he spends $25 a week for eight weeks how much money does he have left from his savings? Explain

Answer 1

Leave out the phrase "for sale."  Trent saved up $500 to pay for his vacation.

When he returns home, he will have $500 - ($25/wk) (8 wks) left:

$500 - $200, or $300 (left).  

Answer 2

First we'll figure out how much he spent. $25 times 8 (weeks)= $200.
Then we subtract that $200 from the total $500. 
$500-$200=$300.
A. Trent has $300 left in his saving
