Ascale drawing has a scale of 0.25 in : 12ft find the length on the drawing for an actual length of 15 ft.

Let the length on drawing for actual length of 15 ft = x inches

And they say that the ratio of drawing length to actual length is 0.25 in : 12 ft

it means we can make a ratio proportion such that

Cross multiplying we get

0.25 * 15 = 12*x

3.75 = 12 x

Divide both sides by 12

x = 0.3125

It means

the length on drawing for actual length of 15 ft = 0.3125 inches

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !

$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
