At a candy store, Erika bought 3 kilograms of cinnamon red hors and 1 kilogram of gummy bears for $21.00. Meanwhile, trene bough
prisoha [69]

The cost of one kilogram of cinnamon red hots is $4.00 and cost of one kilogram of gummy bears is $9.00

Step-by-step explanation:

Let,

Cost of one kilogram of cinnamon red hots = x

Cost of one kilogram of gummy bears = y

According to given statement;

3x+y=21    Eqn 1

3x+3y=39   Eqn 2

Subtracting Eqn 1 from Eqn 2

(3x+3y)-(3x+y)=39-21\\3x+3y-3x-y=18\\2y=18

Dividing both sides by 2

\frac{2y}{2}=\frac{18}{2}\\y=9

Putting y=9 in Eqn 1

3x+9=21\\3x=21-9\\3x=12

Dividing both sides by 3

\frac{3x}{3}=\frac{12}{3}\\x=4

The cost of one kilogram of cinnamon red hots is $4.00 and cost of one kilogram of gummy bears is $9.00
