Question

Claire and Li are evenly sharing the cost of 7 yards of red fabric and 3yards of blue fabric. Find the amount each pays when red fabric is $6.50per yard and blue fabric is $8.00 per yardWrite an algebraic expression for each situation and then evaluate the expression for the given values.

Answer 1

`(7x+3y)/(2)`, $34.75

Explanation:

For the algebraic expression, the red and blue fabric yards (with the unknown variable values) are added and divided by 2, since the cost will be split evenly between Claire, and Li.

Inputting the values to the variables gives $34.75.

Steps:

7(6.50)+3(8.00)

=45.50+24

=69.50

Then divide the cost by two,

69.50/2

=34.75

Claire and Li each pay $34.75.

Answer 2

The required algebraic expression which signifies this relationship is 7x + 3 y = 6.50
