Given:
Beau's grandmother started depositing $500 in a savings account each year in his birthday
Rate of simple interest = 2.5%
Time = 3 years
To find:
The interest.
Solution:
Formula for simple interest:
where, P is principal, r is rate of interest and t is time in years.
Interest for first year is
New principal = 
Interest for second year is
New principal = 
Interest for third year is
Total interest for 3 years is
So, interest after 3 years is $75.
Therefore, the correct options A.

Answer:
169 seconds
3rd lap
0.923 minutes
Step-by-step explanation:
To solve this question, we would use formula for arithmetic progression in solving it.
S(n) = a + (n - 1)d
If a = 25 s
n = 10
d = 16
S(n) = 25 + (10 - 1)16
S(n) = 25 + 9 * 16
S(n) = 25 + 144
S(n) = 169
It takes him 169 seconds to cycle his tenth lap
b
If S(n) = 55.4, what is n
55.4 = 25 + (n - 1)16
55.4 - 25 = (n - 1)16
30.4 = (n - 1)16
n - 1 = 30.4/16
n - 1 = 1.9
n = 1.9 + 1
n = 2.9 approximately 3
Therefore, he's on his 3rd lap
c
Total time cycled is dependent on the total cycles he made, and going to question 2, we were told he made 55.4 seconds of cycle
55.4/60 = 0.923 minutes
Answer:
3672
Step-by-step explanation:
8(477-18)
477-18=459
