Eric Has some quarters and nickels in his pocket he has 30 total count the total value is $3.70 write a system that could be use
d to find you the number of quarters in and n the number of Nickels
1 answer:
Answer:
- q + n = 30
- 0.25q + 0.05n = $3.70
Step-by-step explanation:
After defining variables as ...
q = number of quarters
n = number of nickels
we can write two equations. One of them expresses the total number of coins:
q + n = 30
The other expresses the total value of the coins:
0.25q + 0.05n = 3.70
_____
The solution to these equations is (n, q) = (19, 11).

Answer:
$125
Step-by-step explanation:
Given:
deposit, P= $500
rate,i = 5%
time,t= 5 years
I=P*i*t
where P is principal amount
i is interest rate
t is time
I is simple interest
Putting values we get:
I=500*0.05*5
= 125 !
