Hailey and Livee went to the candy store. Hailey bought a piece of fudge and a piece of bubble gum for
a total of $1.20. Livee bought 2 pieces of fudge and 10 pieces of bubble gum for a total of $3.60. Find
the cost of each fudge and each bubble gum.

a piece of bubble gum cost 0.15 dollars

a piece of fudge cost 1.05 dollars

Step-by-step 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)

check the picture below.

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
