Question

Clarrissa bought a skirt a blouse and a dress. The average cost of the 3 items was $28. The skirt cost $19 snd the blouse cost $14. What was the cost of the dress?

Answer 1

Let x be the cost of the dress.

The total cost of the 3 items is $28*3 = $84

Since the skirt cost $19 and the blouse cost $14, the total cost of the skirt and the blouse is $19 + $14 = $33

Using the total cost of the 3 items, we can write the equation:

$19 + $14 + x = $84

$33 + x = $84

x = $84 - $33

x = $51

So, the cost of the dress was $51.
