Sagot :
The cost of one yard of black fabric is $4.
The cost of one yard of red fabric is $5.
What are the linear functions that represent the question?
2r + b = 14 equation 1
2r + 4b = 26 equation 2
Where:
r = cost of one yard of red fabric
b = cost of one yard of black fabric
What is the cost of each type of fabric?
Subtract equation 1 from equation 2
3b = 12
b = 12 / 3
b = 4
Substitute for b in equation 1
2r + 4 = 14
2r = 14 - 4
2r = 10
r = 10 / 2
r = $5
