Find the percent cost of the total spent on each equipment $36, fees $158, transportation $59
maksim [4K]

Answer: Therefore, Option 'A' is correct.

Step-By-Step  explanation:

Since we have given that

Amount spent on equipment = $36

Amount spent on fees = $158

Amount spent on transportation = $59

Total amount spent by them is given by

36+158+59=\$253

Percent cost of equipment of the total amount is given by

\frac{36}{253}\times 100=14.2\%

Percent cost of fees of the total amount is given by

\frac{158}{253}\times 100\\\\=62.45\%

Percent cost of transportation of the total amount is given by

\frac{59}{100}\times 100\\\\=23.3\%

Hence, Percent cost of the total spent on each is

14%, 62%, 23%.

Therefore, Option 'A' is correct.
