Brainliest please!

Equation 1, number of coins:

p + n = 20

Equation 2, amount:

.01p + .05n = .56

System to solve:

    p +      n   =    20

.01p + .05n   =   .56

--------------------------

Solve by substitution:

p + n = 20

p = 20 - n

.01(20 - n) + .05n  = .56

.20  - .01n + .05n = .56

Combine terms:

.04n = .36

n = 9

Jayden has nine nickels

From equation 1:

p + 9 = 20

p = 11

Jayden has 11 pennies
