Question

A dress cost twice as much as a skirt. Mom bought 3 dresses and 2 skirts. She gave the cashier $1000 and received $300 in change.How much did a dress cost?

Answer 1

Answer:

$175 = Cost of single dress

Step-by-step explanation:

It is provided that cost of dress is twice that of a skirt.

Let say, cost of skirt = x

Total things bought 3 dresses and 2 skirts.

Cost of single dress = 2x

Cost of all items = 3 $\times$ 2x + 2 $\times$ x = $1,000 - $300 = $700

6x + 2x = $700

x = 700/8 = $87.50

Cost of single dress = 2x = $87.50 $\times$ 2 = $175
