A hairdresser is deciding where to open her own studio. If the hairdresser chooses Location A, she will pay $1200 per month in r

Ymorist [56]

She will need to cut 26.6 haircuts a month a location A to break even (1200/45 = 26.6) so roughly 27 haircuts to make a profit

She will need to cut 30 haircuts at location B to break even (1800/60 = 30) and 31 hair cuts to see a profit.

She will need to cut 30.67 haircuts at location A and 33 haircuts at location B to make the same profit at either location (Roughly $180).

30.67 x 45 = 1380.15 - 1200 = 180

33 x 60 = 1980 - 1800 = 180

The table represents a function.

Elenna [48]

f(5) is -8 ⇒ 1st answer

Step-by-step explanation:

Function is a relation between set of of ordered pairs (x , y),and every x has only one y

Examples:

{(-1 , 2) , (2 , 4) , (5 , -3)} is a function because x = -1 has only y = 2, x = 2 has only y = 4 and x = 5 has only y = -3
{(-2 , 4) , (0 , -1) , (-2 , 5)} is not a function because x = -2 has y = 4 and 5

The notation of the function is f(x) = y

The table:

→ x : f(x)

→ -4 : -2

→ -1 : 5

→ 3 : 4

→ 5 : -8

From the table

∵ x = -4

- The corresponding value of y to x = -4 is -2

∴ f(-4) = -2

∵ x = -1

- The corresponding value of y to x = -1 is 5

∴ f(-1) = 5

∵ x = 3

- The corresponding value of y to x = 3 is 4

∴ f(3) = 4

∵ x = 5

- The corresponding value of y to x = 5 is -8

∴ f(5) =-8

f(5) is -8

For how many movies is the cost of the plans the same?

sesenic [268]

Answer:

For 36 movies the cost of both the plans is same.

Step-by-step explanation:

Let us assume foe m movies, both the plans cost same.

Now, PLAN A:

Annual Fee = $45

Cost per movie = $2.50

⇒The cost of watching m movies = m x (Cost of 1 movie)

= m x ($2.50) = 2.5 m

So, the total cost of Plan A = Annual Fee + Cost of m moves

= 45 + 2.50 m

PLAN B:

Cost per movie = $3.75

⇒The cost of watching m movies = m x (Cost of 1 movie)

= m x ($3.75) = 3.75 m

ACCORDING TO QUESTION:

for m movies, Cost of plan A = Cost of plan B

⇒45 + 2.50 m = 3.75 m

or, 3.75 m - 2.5 m = 45

or, m = 45/1.25 = 36

or, m = 36

Hence, for 36 movies the cost of both the plans is same.
