An online store sells dvds for $10 each. the shipping charge for an entire order is $5.50. frank orders d dvds. write an expression that represents the total cost of frank's dvds

total cost = 10d +5.50

Step-by-step explanation:

Hi, to answer this question we have to write an equation with the information given:

So, the total cost is the sum of the shipping cost (5.50) and the product of the cost of each DVD (10) and the number of DVDs ordered (d)

Mathematically speaking:

Total cost = 10d +5.50

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.
