Given:

Total number of coins = 20

Total cost of nickel and dime = $1.40

To find:

The number of nickels.

Solution:

Let the number of nickels be "n" and number of dimes be "20 - n".

Value of nickel = 5 cents

Value of dime = 10 cents

$1.40 = 140 cents

Cost of nickel + Cost of dime = $1.40

Subtract 200 from both sides.

Divide by -5 on both sides.

Hence Jenna have 12 nickels.
