You have to find a like term. the answer is 4b because when you do b x 2, that is doubling the variable of b. when you take b away from b+b, or b x 2, that is b.
the 4 is outside of the parentheses, so you multiply it, as the coefficient, by b. so this cannot be solved, only simplified to 4b

4b because you distribute the 4 to get 8b - 4b so that equals 4b

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.
