POR FAVOR ME AJUDEM PRECISO DISSO PARA DIA 27

Part 1) The price of each dozen of oranges is R$3.00 and the price of each dozen of bananas is R$4.00

Part 2)

Step-by-step explanation:

The complete question in English is

3 ladies went to the fair. Ms. Nice spent R$25.00 on 3 dozen oranges and 4 dozen bananas, Ms. Maria bought 4 dozen oranges and 3 dozen bananas, and Ms Neusa spent R$20.00 on 5 dozen bananas.

Part 1) Find the price of each dozen of bananas and each dozen of oranges

Part 2) How much did Mrs. Maria spend?

Part 1) Find the price of each dozen of bananas and each dozen of oranges

Let

x ----> the price of each dozen of oranges

y ----> the price of each dozen of bananas

we know that

Ms. Nice

----> equation A

Ms. Maria

Ms. Neusa

----> equation B

step 1

Find the value of y

Solve equation B

Divide by 5 both sides

step 2

Substitute the value of y in the equation A

solve for x

subtract 16 both sides

divide by 3 both sides

therefore

The price of each dozen of oranges is R$3.00 and the price of each dozen of bananas is R$4.00

Part 2) How much did Mrs. Maria spend?

we know that

Ms. Maria

substitute the value of x and the value of y  in the expression above

step-by-step explanation:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

step-by-step explanation:

given that megan owns a clothing boutique.

the profits of 2010, 11, are recorded and shown as follows:

years since     2010 0     1     2     3       4       5

profits made in 1000's   39       84     111     120   111     84

we find that profit gradually increases form 2010 to 2013 upto 120,   then starts decreasing.

the profits for 2012 and 2014 are the same while that of 2011 and 2015 are also the same.

this shows that there is symmetry about the line profit = 120000

hence answer is:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.
