It would cost $21 because each pound is $3. So 7 pounds x $3 = $21 for 7 pounds
x = numărul de monede de 2 euro
y = număr de bancnote de 5 euro
2x + 5y = 25
x + y = 8
y = 8 - x
2x + 5(8 - x) = 25
2x + 40 - 5x = 25
-3x = -15
x = 5
x + y = 8
5 + y = 8
y = 3
numărul de monede de 2 euro = 5
număr de bancnote de 5 euro = 3
