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.
Step-by-step explanation:
f (10) = 3×10 - 8
= 30 - 8
= 22
f (3) = 3×3 - 8
= 9 - 8
= 1
f(10) - f (3) = 22 - 1
= 21
