Step-by-step explanation:
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
Dividing both sides by 2
Putting y=9 in Eqn 1
Dividing both sides by 3
The cost of one kilogram of cinnamon red hots is $4.00 and cost of one kilogram of gummy bears is $9.00
