Write an equation for the given word problem.
anne deposits $300 in her bank account. now her balance is $450. which equation can be used to find the amount, x, in her bank account?
300 + 450 = x
x + 300 = 450
300x = 450

x + 300 = 450 is the correct answer. This is becuause the unknown amount, x, is how much she put in the bank. $450 is her total, so it would be equal to 450. If she already had 300, you need to firgure out what she added to 300 to make the answer 450, so the correct answer is x + 300 = 450.

ab will be equal to

$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
