Answer:
monica because with 3.4 % that is more than 2.3% and that is what they want to know so its monica
Step-by-step explanation:
The formula for calculating simple interest is given by :
S.I = [tex]\frac{ptr}{100}[/tex]
For Monica
S.I = 300 x 3.4 x 1 / 100
S.I = $10.2
For Paul
S.1 = 400 x 2.4 x 1 / 100
S.I = $9.6
Therefore : Monica earned more interest
Monica's intrest rate is 1,224 and paul's is 840 so it would be monica.
