A shoe store buys a pair of boots from a supplier for $45. The store's manager decides on a markup of 35%. What is the new price

Gnom [1K]

Answer:

The new price of the books = $60.75

Step-by-step explanation:

As the original price is: $45

As the markup is: 35% = 35/100 = 0.35

The Markup on the original price is:

0.35 × 45 = $15.75

Hence, the new price of the boots:

$45 + $15.75 = $60.75

Therefore, the new price of the books = $60.75

Work the following pricing problems for services rendered. (For all calculations use hundredths.)

Lesechka [4]

Answer:

Hourly Rate = $12.22 per hour

Step-by-step explanation:

$\text{Labor Time = }4\tfrac{1}{2}=4.5\thinspace{ hours}$

Overhead Rate = 95%

Retail price of parts = $134.75

Total cost of job = $241.98

Cost of labor = Total cost - Retail price

= 241.98 - 134.75

= $107.23

Now, labor works for 4.5 hours and ears a total amount of $107.23

$\implies\text{Amount earned in one hour or hourly rate = }\frac{107.23}{4.5}\\\\\implies \text{Hourly rate = }\$23.83\text{ per hour}$

Now, Labor will get 95% overhead rate

⇒ The labor is getting 100% already but an overhead of 95% is also given

$\text{So, Hourly Rate = }\frac{23.83}{1+0.95}\\\\\bf\implies\textbf{Hourly Rate = }\$12.22\textbf{ per hour}$
