Question

Miss Goh bought 6 blouses, 2 skirts and 2 dresses for $560. A blouse and a skirt cost $107. A blouse and a dress cost $134. What was the cost of a dress?

Answer 1

$95 FOR A DRESS

Explanation:

Let's rearrange the given:

She bought a blouse and skirt for two, a blouse and a dress for two, and a blouse for two.

A blouse and a skirt cost $107

A blouse and a dress cost $134

blouse cost x dollars

The equation:

2($107) + 2($134) + 2x = $560

SOLUTION:

$214 + $268 + 2x = $560

2x = $560 - $214 - $268

2x = $78

x = $39 for a single blouse

FIND THE COST OF DRESS:

A blouse and a dress cost $134 - $39 for a single blouse

$134 - $39 = $95

$95 IS THE COST OF DRESS
