Yuri [45]

Answer:

As per the statement:

Mr. Roseanne will buy $12\frac{1}{2}$ pounds beef for for a cookout.

⇒ Weight of the beef he buy = $\frac{25}{2}$ pounds.

It is given that:

The price for the first 3 pounds of beef is $4.99 per pound.

then;

the price for 3 pounds he will pay= $3 \times 4.99 =\$ 14.97$

After that, the price is $4.49 per pound.

Remaining weight of beef left = $\frac{25}{2} -3 = \frac{19}{2}$ pounds.

then;

the price of $\frac{19}{2}$ pounds he will pay = $\frac{19}{2} \times 4.49= \$42.655$

now, total money he will pay for the $12\frac{1}{2}$ pounds beef = $14.97+42.655 = \$57.625$

Therefore, $57.625 will Mr. Roseanne pay for the beef

An investment firm invested in two companies last year. They invested $11,000 in Company A and made a profit of 24% . They inves

Tema [17]

First off, "whatever%" of "anything" is just (whatever/100) * anything

part A)

so... firm A got 11,000 invested, turned a profit of 24%, how much is 24% of 11000? well (24/100) * 11000

firm B got 14,000 invested, and returned 15% in profits, how much is 15% of 14000? (15/100) * 14000

part B)

for the amounts above, we get 2640 and 2100 respectively

so, the total profit "amount" is 2640 + 2100 or 4740

the total investement was 11000+14000 = 25000

if 25000 is the 100%, how much is 4740 in percentage?

$\bf \begin{array}{ccllll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
25000&100\\
4740&x
\end{array}\implies \cfrac{25000}{4740}=\cfrac{100}{x}$

solve for "x"
