7. A company manufactures shaving sets for $5 each and sells them for $7 each. How many shaving sets must be sold for the
Mandarinka [93]

Answer:

$30,000

Step-by-step explanation:

profit = amount of sales - expenses

The company spends $5 on each set. it sells each set for $7.

The profit on each set is $7 - $5 = $2.

For each set the company sells, it makes $2 of profit.

It cost the company $45,000 to start production, and the company wants a profit of $15,000. The company needs to earn $45,000 + $15,000 = $60,000 in profits.

Since the profit per set is $2, the number of sets it needs to sell is

$60,000/$2 = 30,000

Answer: 30,000 sets

In a fireplace, about 3/4 of an 18 inch log will burn in 1/3 of an hour. How many hours will it take to burn 2 1/2 logs
Karo-lina-s [1.5K]
\bf \begin{array}{ccll}
\stackrel{burned}{log}&\stackrel{time}{hr}\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
\frac{3}{4}&\frac{1}{3}\\\\
2\frac{1}{2}&h
\end{array}\implies \cfrac{\frac{3}{4}}{2\frac{1}{2}}=\cfrac{\frac{1}{3}}{h}\implies \cfrac{\frac{3}{4}}{\frac{2\cdot 2+1}{2}}=\cfrac{\frac{1}{3}}{\frac{h}{1}}

\bf \cfrac{\frac{3}{4}}{\frac{5}{2}}=\cfrac{1}{3}\cdot \cfrac{1}{h}\implies \cfrac{3}{4}\cdot \cfrac{2}{5}=\cfrac{1}{3h}\implies \cfrac{6}{20}=\cfrac{1}{3h}\implies 6\cdot 3h=20\cdot 1
\\\\\\
18h=20\implies h=\cfrac{20}{18}\implies h=\cfrac{10}{9}\implies h=1\frac{1}{9}

about 1 hour and 6 minutes with 36 seconds.
