Answer:
6 dresses
Step-by-step explanation:
Given: sales price is $d
Regular price is 3 times of sales price
Janine has money to buy 2 dresses at regular price.
Now, finding the number of dresses Janine can buy at the sales price, if sale price is d
Regular price= [tex]3\times d= 3d[/tex]
Janine has total money= [tex]3d\times 2= 6d[/tex] (∵ regular price is 3d)
∴ Number of dresses bought by Janine= [tex]\frac{Total\ money}{sale\ price\ of\ one\ dress}[/tex]
⇒ Number of dresses bought by Janine= [tex]\frac{6d}{d} = 6\ dresses[/tex]
∴ Number of dresses bought by Janine is 6.
