Answer:

13 years old

Step-by-step explanation:

2x - 4

11-5=6

6 x 2 = 12

12 - 4 = 8

8 + 5 = 13

CHECKING JUST TO MAKE SURE:

13 - 5 = 8

11 - 5 = 6

6 x 2 = 12

12 - 8 = 4

You can now tell that it is correct.

<h2><u>Solution 1</u> :</h2>

Cost of $1\frac{1}{3}$ pounds of gummy bears = $4.40

Cost of 1 pound of gummy bears :

$= 4.40 \div 1 \frac{1}{3}$

$= \frac{440}{100} \div \frac{4}{3}$

$= \frac{440}{100} \times \frac{3}{4}$

$= \frac{1320}{400}$

$= \frac{1320 \div 20}{400 \div 20}$

$= \frac{66}{20}$

$= \frac{66 \div 2}{20 \div 2}$

$= \frac{33}{ 10 }$

$= 3 \frac{3}{10}$

$= \color{plum}\bold{\$3.3}$

Therefore, 1 pound of gummy bears = <u>$3.3</u>

<h2><u>Solution 2</u> : </h2>

Cost of 1 pound of gummy bears = $3.3

Money Daniel has = $1.00

Quantity of gummy bears he can afford :

$= 1 \div 3.3$

$= 1 \div 3 \frac{3}{10}$

$= 1 \div \frac{33}{10}$

$= 1 \times \frac{10}{33}$

$= \frac{10}{33}$

$= 0.30$

Therefore, Daniel will be able to buy <u>0.30 pounds</u> of gummy bears from Jio.

If it costs $75,000 to put on an event and total revenue is $135,000, what is the profit as a percentage of revenue?

Tems11 [23]

1st find total profit by subtracting the cost from the total revenue:

135,000 - 75,000 = $60,000 profit

Now divide the profit by the total revenue:

60,000 / 135,000 = 0.444 = 44.4% = 44% profit
