Answer:
C = 14.99n + 9.99
Explanation:
From the information given in the question, we already have the slope which is 14.99.
To find the y-intercept (which in this case represents the same delivery fee no matter how many Blu-rays are purchased) we can use the order for 10 Blu-rays.
Multiply 14.99 by 10 to get the cost of all the DVDs.
(14.99)(10) = 149.90
To find the value of the delivery fee we can minus 149.90 from 159.89:
159.89 - 149.90 = 9.99
The cost of delivery is $9.99
Therefore, we can write the final equation like this:
C = 14.99n + 9.99
I hope this helps!!
