Sagot :
The cost of each spiral notebook is $3 and the cost of each book cover is $2
Given that Alexis and her sister bought school supplies. Alexis bought 5 spiral notebooks and 6 book covers for $27. Her sister bought 4 spiral notebooks and 2 book covers for $16 and asked to find out the cost of each spiral notebook and each book cover.
Let's assume spiral notebooks as "x" and book covers as "y".
As a result, two linear equations in two variables will be formed.
⇒5x+6y=$27; Let's assume this equation as A
⇒4x+2y=$16; Let's assume this equation as B
Multiply equation B with 3
⇒12x+6y=$48; Let's assume this equation as C
Equation c- Equation A
⇒$48-$27=7x
⇒7x=$21
⇒x==$3
The cost of the spiral notebook is $3
From equation A
⇒5($3)+6y=$27
⇒$15+6y=$27
⇒6y=$12
⇒y=$2
The cost of the book cover is $2
Therefore,The cost of each spiral notebook is $3 and the cost of each book cover is $2
