The perpendicular line would have a slope of 1/3.
Perpendicular lines have opposite and reciprocal slopes.
To do the opposite, take the original slope (-3) and change the sign (3).
To do the reciprocal, take the slope we changed (3) and flip it as a fraction (1/3).
This gives us a new slope of 1/3.
If she already had savings of $125.75, and she earned $185 at her summer job, that means she has a total of $310.75 ($125.75 + $185 = $310.75).
If she then buys a $23.50 T-shirt, her total savings amounts to $287.25, because $310.75 - $23.50 = $287.25.
So the final answer is $287.25 :)
