Suppose you have a $8-off coupon at a fabric store. You buy fabric that costs $7.50 per yard. Write an equation that models th
e total amount of money y you pay if you buy x yards of fabric. What is the graph of the equation?
2 answers:
Answer:
= 7.5x-8
Step-by-step explanation:
Total cost = cost per yard * yard of fabric - coupon
total cost = 7.5 x - 8
y = 7.5x-8
Answer:
Step-by-step explanation:
For the equation, the amount of money is , and the number of yards is
.
So, the problem says that the persona already have $8, which is constant, it wont' variate, that is, this is the independent term.
Then, it says the the fabric costs $7.50 per yard, and refer to yards, so this term would be
.
Therefore, the equation to model this problem would be:

I'm assuming this is multiple choice and you forgot to post the answers. I'll take a guess and say it probably looks something like this:
Because you can't take the square root of a negative number without getting an imaginary result, resulting in the function having a closed domain limit.
