Answer:
$16,875
Step-by-step explanation:
The amount received per year is $15,000 and the CPI increased from 144 to 162
Inflation rate = (New CPI - Old CPI)/Old CPI * 100
Inflation rate = 162-144/144 * 100
Inflation rate = 0.125
Inflation rate = 12.5%
Amount received = $15,000 * 12.5% = $1,875
==> $15,000 + $1,875 = $16,875
So, Grandmother will receive $16,875
