On black friday the new lol phone was discounted 45%. if the original price was $250.00 and the sales tax is 6%, what would be the total cost for this item?

$145.75

Step-by-step explanation:

First step is to find the price after discount

Discount = original price * discount percent

                = 250 *.45

                  =112.50

The discounted price is the original price less the discount

Discounted price = original price-discount

                             =250-112.50

                               =137.50

 Now we need to calculate the tax.  The tax is the discounted price times the tax rate.

Tax=discounted price * tax rate

     = 137.5 *.06

      8.25

To find the total cost, we add the tax to the discounted price

Total cost = discounted price + tax

                = 137.5 + 8.25

                =145.75

$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
