You can put this solution on YOUR website!
Let number of 10 centavos be "x"
The number of 5 centavos is "x+19"
Value of 10 centavos is (10)x
Value of 5 centavos is (5)(x+19) = 5x + 95
EQUATION:
Value of 10 centavos + Value of 5 centavos = 3050
10x + 5x + 95 = 3050
15x = 2955
x = 197 ( number of 10 centavos)
x + 19= 216 (number of 5 centavos)
