Answer:
$18,750
Explanation:
Step 1.
150,000 x 1/2 = 75,000
(this is the amount going to his daughter)
Step 2.
150,000 x 3/8 = 56,250
(this is the amount going to his favorite nephew)
Step 3.
75,000 + 56,250 = 131,250
Step 4.
150,000 - 131,250 = 18,750
(this is the amount left over for his only grandson)
