Answer: He will pay $630 over the course of the loan.
Step-by-step explanation:
Formula for simple interest :
S.I. = PRT, where P=principal amount , R =rate of interest ( in decimal), T=time (in years)
As per given ,
P = $1,400 , t = 5 years , r = 9% = 0.09
Simple interest = (1400) x (0.09) x (5)
⇒ Simple interest = $ 630
Hence, he will pay $630 over the course of the loan.
Step-by-step explanation:

To solve this is you have to find the price per ounce for each item by simply dividing the price by the ounces.
For the oat cereal divide $3.90 by 15
3.90/15
.26 per ounce
For the rice cereal divide $3.30 by 11
3.30/11
.30 per ounce
The oat cereal costs less per ounce since it is only .26 per ounce whereas the rice cereal is .30 per ounce.
Hope this helps!
