Answer:
true
Step-by-step explanation:
If Alexa's mom paid 1/2 of the $450:
$65
if Alexa's mom paid 1/2 of the remaining price:
$145
Alexa's mom paying 1/2 the $450:
$450 divided by 2 = $225
$225 - $120 = $105
$105 - $40 = $65
Alexa has $65 left to pay
Alexa's mom paying 1/2 of the remaining price after the student discount and Alexa payed $120:
$450 - $120 = $330
$330 - $40 = $290
$290 divided by 2 = $145
