Answer:
B. 24d + 4; $76
Step-by-step explanation:
Part 1: If the online store charges $24 per DVD, this is the same as saying "24 multiplied by the number of DVDs bought".
It's given that "d" represents the number of DVDs
- So the first part of the variable expression is: 24d
If the online store also charges an additional $4 per <em>order,</em> that means that it's only $4 extra for the whole order. NOT per DVD you buy.
Part 2: If someone were to buy 3 DVDs, that would mean that d = 3.
To find the total cost, substitute 3 for d into the expression.
- 24d + 4
- 24(3) + 4
- 72 + 4 = 76
- Result: $76
The answer is -4,0 4,8 because u would solve for one variable in one of the equations and then substitute the result into the other
The operation applied is division.
a simple explanation is that the quantity decreases if you move the decimal to the left, which is the case for division
A power of 10^-4 is involved (you get a negative sign if you shift the decimal to the left: which is another explanation to the above question)
