Answer:
The Greys will pay less interest if they take the second option: $19,500 - $19,350 = $150
Explanation:
First option will cost the Greys = 6.5% x $60,000 x 5 years = $19,500 in interests
Second option will cost the Greys = (6,25% x $60,000 x 5 years) + ($60,000 x 1%) = $18,750 + $600 = $19,350
The Greys will pay less interest if they take the second option: $19,500 - $19,350 = $150
