Answer:
Ok nice and easy, you earn about 0.04% more interest
Explanation:
So lets do an easy number 100 for example.
100(0.2) = 2 2+100=102 102 is for A
100(0.025) = 2.5 100+2.5=102.5 102.5 is for B
Find the percentage change
new-old/old
102.5-102=0.5
0.5/102= 0.0043 (infinity)
Round it to a percent and the nearest percent
0.04%
We can do a check with a different number
1000(0.2)= 20 20+1000=1020
1000( 0.025)= 25 25+1000= 1025
find the percentage change
1025-1020=5
5/125= 1/25
1/25= 0.04
so there you go :)
