commission?

Answers

Answer:

$2245

Step-by-step explanation:

7% ff $1000 = $70

0.07 × 1000

Subtract 1000 from 15,500

15% of $14,500 = $2175

0.15 × 14,500

2175 + 70 = $2245

On a 1/5 scale drawing of a car, one part is 8 inches long. How long will the actual car part be?

Answers

If it's one fifth scale, take it times five to get the whole scale. 8 times five equals 40. The car is 40" long, 3' 4" long, or three and one third feet long.

Answer:

The actual length of the given car part is 40 inches.

Step-by-step explanation:

Given : Scale of drawing of a car is (1)/(5)

Also, given one part is 8 inches long.

We have to find the actual length of the given car part.

Since, the given scale decreases the actual length by a factor of (1)/(5)

So, The actual length will be

New length = (1)/(5) × actual length

Thus, Actual length will be

Actual length = 5 ×  new  length

 Actual length = 5 × 8 = 40 inches.

So,  The actual length of the given car part is 40 inches.
