Question

Devi bought 7 skirts at $x each, n skirts at $12 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:

7 skirts at $x each,

n skirts at $12 each,

(2n + 1) skirts at $15 each

4 skirts at $3x each

To find:

The total cost of the skirts Devi bought

Solution:

Here we are given the cost of 1 piece of every type of skirts.

So,

We will first find the total cost of each type of skirts bought by Devi separately:

The cost of 7 skirts = $\ 7x$

The cost of n skirts = $\ 12n$

The cost of (2n + 1) skirts = $\ 15(2n + 1) = \ (30n + 15)$

The cost of 4 skirts = $4 \times \ 3x = \ 12x$

Now, we will add all the cost to get the final answer to the total cost.

∴ The total cost of the skirts is,

=  $\ 7x + \ 12n + \ (30n + 15) + \ 12x$

= $\ [7x + 12n + 30n + 15 + 12x]$

= $\bold{\ [19x + 42n + 15]}$

Thus, the total cost of the skirts she bought is $\underline{\ [19x + 42n + 15]}$.
