Answer:
Paul earned $2.6 more interest than Monica.
Step-by-step explanation:
Giving the following information:
Monica:
Initial investment= $300
Interest rate= 4.2%
Paul:
Initial investment= $400
Interest rate= 3.8%
<u>To calculate the income earned, we need to use the following formula:</u>
I= P*r*t
P= principal
r= interest rate
t= time
Monica:
I= 300*0.042*1= $12.6
Paul:
I= 400*0.038*1= $15.2
Paul earned $2.6 more interest than Monica.
Pythagoras: A^2 + B^2 = C^2 where c is the side opposite the hypotenuse (opposite the right angle) and B and C are the other sides. Trigonometry: SOH CAH TOA where you can use their formula where sin = opposite/ hypotenuse Cos= adjacent/ hypotenuse Tan= opposite/ adjacent
