Question

Susan has a collection of 70 nickels and dimes if the number of nickels as four times a number of times how many nickels and how many dimes does she have

Answer 1

Answer:

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

Susan has 14 dimes and 56 nickels
