each, (2n + 1) skirts at $15 each and 4 skirts at
$3x each. Find the total cost of the skirts she bought.​

Answer 1

Given: Devi bought some skirts at the given costs.

To find: The total cost?

Solution:

Now we have given that devi bought some skirts.

Those costs:

                 7 skirts at $ x each

                 n skirts at $ 12 each

                 (2n + 1) skirts at $ 15 each

                 4 skirts at $ 3x each

So the total cost of the skirts is:

                 Total cost = x + 12 + 15 + 3x

                 Total cost = 4x + 27

Answer:

                 So the total cost is $ 4x + 27.
