Answer:
Let's call the cost of a blouse "b" (in dollars). Then, according to the problem, the cost of a dress is 3/4 of the cost of a blouse, or (3/4)b.
We know that Vicky paid $350 for 3 dresses and 4 blouses, so we can set up the equation:
3(3/4)b + 4b = 350
Simplifying this equation, we get:
9/4 b + 4b = 350
Combining like terms, we get:
17/4 b = 350
To solve for b, we can multiply both sides by 4/17:
b = 350 × 4/17 = $82.35 (rounded to two decimal places)
Therefore, the cost of a dress is:
(3/4)b = (3/4)($82.35) = $61.76 (rounded to two decimal places)
So each dress cost $61.76.
