Michelle has a starting balance on a gift card for $300. she buys several dresses at $40. after her purchases she has $140 on the gift card. how many dresses did she buy?

i need writing the equation and you < 3

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)

the line of

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
