Heather purchased a prepaid phone card for $15 . Long distance calls cost 16 cents a minute using this card. Heather used her card only once to make a long distance call. If the remaining credit on her card is $12.76 , how many minutes did her call last?

14 minutes

Step-by-step explanation:

In order to get the answer, we have to subtract the original amount of money on the phone card by the amount left over after the call:

15 - 12.76 = 2.24

Then, we divide this number by 0.16:

2.24 / 0.16 = 14

So, Heather's call lasted 14 minutes

Hope this helps :)

$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
