Answer:
$392. No they don't have enough money to pay for the trip.
They need $255 more dollars, which would take 14 weeks and 2 days.
Step-by-step explanation:
18 x 4 = 72
320 + 72 = 392
647 - 392 = 255
255/18 = 14.2
32 inches cubed
Multiply the length by the width: 4*4=16
Multiply by 12: 16*1/2=8
Multiply by height: 4*8=32
