If the value of the car decreases by 8% every year it would take 13 years for the car to be worth
$10000.00.
The answer is 72.1.you should dot infront sizes and then equals them
Equation 1. N+D=500
equation 2 5N+10D=3000
This is for equation 1
N=500-d
Substitute into equations 2 and solve for D
5N+10D=3000
5(500-D)+10D=3000
2500-5D+10D=3000
5D=500
D=100
Lets go back the equation 1
N=500-D
N=500-100
N=400
there are 400 Nickles and 100 Dimes
50,70,80,100,110,130 that would be it
