Susan has 14 dimes and 56 nickels
Explanations:Let the number of nickels be n
Let the number of dimes be d
The number of nickels is as four times the number of dimes
n = 4d.......(1)
She has a total collection of 70 nickels and dimes
n + d = 70.......(2)
Substitute equation (1) into equation (2)
4d + d = 70
5d = 70
d = 70/5
d = 14
Substitute the value of d into equation (1)
n = 4d
n = 4(14)
n = 56
