RUDIKE [14]

Answer:

The total sales of Boutique last week = $1300

Step-by-step explanation:

Given that:

Percent of sales came from leggings = 30%

Worth of leggings sold = $390

Let,

x be the total sales in the week.

30% of x = 390

\frac{30}{100}x=390

0.3x = 390

Dividing both sides by 0.3

\frac{0.3x}{0.3}=\frac{390}{0.3}\\x=1300

Hence,

The total sales of Boutique last week = $1300
