Answer:
P=$880,I=$92.40
P=$675,I=$94.50
P=$770,I=$96.79
Step-by-step explanation:
Simple interest rate is the interest eared on principal amount only over time:

#$880 at 5.25% for 2 years

Hence, the interest earned is $92.40
#$675 at 3.5% for 4 years:

Hence, the interest earned is $94.50
#$770 at 4.19 for 3 years:

Hence, the interest earned is $96.79
9.66
^ This is the tenths place.
Look at the number after it, if it's 5 or more we round up, if it's 4 or less we round down.
The number is 6, so we round up to 9.7.
