Answer:
a piece of bubble gum cost 0.15 dollars
a piece of fudge cost 1.05 dollars
Explanation:
Let x be the cost of a pieces of fudge and y be the cost of a pieces of bubble gum
Hailey : x + y = 1.20
Therefore = > x = 1.20 - y
Livee : 2x + 10y =3.60
2x + 10y = 3.60
2(1.20 - y) + 10y = 3.60
2.4 - 2y +10y = 3.60
2.4 + 8y = 3.60
8y = 1.2
y = 0. 15 (dollars)
x + y = 1.20
x + 0.15 = 1.20
x = 1.05 (dollars)
