The formula to calculate the compound amount is given by :-
, where P is the Principal amount invested , r is the rate of interest ( in decimal ), and t is the time period ( in years).
As per given , we have
P= $500 , r= 6%=0.06
Then the formula to find the compound amount after t years :
(Put values of P and r in the formula)
For t=1
Jack will have $530 after 1 year.
For t=2
Jack will have $561.8 after 2 years.
For t=5
Jack will have $669.11 after 5 years.
For t=10
Jack will have $895.42 after 10 years.

Answer:
x+y<20andx+5y>40
Step-by-step explanation:
The inequality for the number of coins is ...
x + y < 20
The inequality for the value of the coins is ...
x + 5y > 40
They can be the same price at 40 miles because 50+1(40) is 90 and 10+2(40) is 90
