Answer:
the bank's profits will decrease by $0.10 per $100 of assets
Step-by-step explanation:
increase in revenues increase in expenses
$40 x 5% = $2 $50 x 3% = $1.50
$40 x 6% = $2.40 $50 x 4% = $2
+$0.40 + $0.50
if the interest rates increase, the bank's revenues will increase by $0.40 for every $100 worth of assets, but its expenses will also increase and in a higher proportion. The bank's expenses will increase by $0.50, so the net change will be $0.40 - $0.50 = -$0.10 or $0.10 less profits
