Hi there! Interest on the first loan is 800×.075×2=120. The interest on the second loan is 138-120=18. Now, we have to use the simple interest formula. 18=P×.03×2=300. Therefore, the answer is $300.
Lets say pi is 3.14
The area of a circle is: pi*radius squared
The radius is half the diameter so it is 5 inches.
3.14*5 squared 2
3.14*25
78.5inches squared
Answer:
6.48 dollars total,
Step-by-step explanation:
First, you would want to multiply the amount of money per pound, by the amount of pounds. 1.60 multiplied by 4 1/2 or 4.5, would equal to 7.2 dollars. In order to find 10% of 7.2, your would need to multiply 7.2 by 0.10, which would give you 0.72. Then you would subtract 7.2 by 0.72 to get 6.48. So your answer would be 6.48 dollars. Hoped this helped.
