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)

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
