Question

From 9:00 AM to 12:00 PM, Linda's stock portfolio increased in value from $2,500 to $6,400. If Linda's portfolio continues to grow at this rate, how much will it be worth at 2:30 PM?

Answer 1

9:00am - 12:00pm = 3 hours
$6,400-$2,500=$3,900
$3,900/3= $1,300 per hour
12:00pm - 2:30pm = 2.5 hours
$1,300 x 2.5= $3,250
$6,400 + $3250 = $9,650
