Answer

140=300-40x

Step-by-step explanation:

x is the number of dresses and to get 140, you have to subtract the dress cost from the original value

Answer:

She bought 6 dresses.

Step-by-step explanation:

First we must subtract $40 by $300. If you subtract $40 by $300, 6 times it equals $140. (hope this helped)
