The cost of one roll of plain wrapping paper is $8 and one roll of holiday wrapping paper is $14.
Step-by-step explanation:
Let,
Cost of one plain wrapping paper = x
Cost of one holiday wrapping paper = y
According to given statement;
6x+y=62 Eqn 1
3x+10y=164 Eqn 2
Multiplying Eqn 2 by 2
Subtracting Eqn 1 from Eqn 3
Dividing both sides by 19
Putting y = 14 in Eqn 1
Dividing both sides by 6
The cost of one roll of plain wrapping paper is $8 and one roll of holiday wrapping paper is $14.
