A. the rate of change is __ per yard. b. write a direct variation equation for the cost Y that will be spent on X yards. __

c. what will be the total cost for 8 yards of fabric?

d. if the total cost of buying fabric is $42, how many yards were bought?

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
