A store sells used DVDs for $8 each and used videotapes for $6 each. Write a function rule to represent total selling price of DVDs and videotapes. Then use the function rule to find the price if 5 DVDs and 3 videotapes
if the cost is c, then
c(d,v) = 8d + 6v
c(5,3) = 8*5 + 6*3 = 58
8d+6v=14+5+3=22
8d+6v=14+5+3=22 is wrong but c(d,v) =8d + 6v
c(5,3) =8*5+ 6*3 = 58
IS correct
hey i have a question will u answer it for meh
it is 8d+6v=58
this sucks
To write a function rule to represent the total selling price of DVDs and videotapes, let's define a few variables:
Let's call the number of DVDs "d" and the number of videotapes "v".
Given that each DVD costs $8 and each videotape costs $6, the function rule to calculate the total selling price can be written as:
Total selling price = (8 * d) + (6 * v)
To find the price if 5 DVDs and 3 videotapes are purchased, we can substitute these values into the function:
Total selling price = (8 * 5) + (6 * 3)
Calculating this expression will give us the answer:
Total selling price = 40 + 18
Total selling price = $58
Therefore, the price for 5 DVDs and 3 videotapes would be $58.
