Answer: $409.50

ok so, original price 450. 9% discount. discount price is the price after discount, so lets find the discount value. 9% of 450 is 40.5. now subtract that from the original price of 450. 450-40.5=409.50

Cameroon corp. manufactures and sells electric staplers for $15.90 each. if 10,000 units were sold in december, and management f

Serga [27]

Sales in December = 10,000*15.90 = $159,000

For 5% forecast growth each month;

Sales in January = (1+0.05)*Sales in December = 1.05*159,000 = $166,950
Sales in February = (1+0.05)*Sales in January = 1.05*166,950 = $175,297.50

The company should budget for $175,297.50 sales in February.

A water tank has a square base of area 5 square meters. Initially the tank contains 70 cubic meters. Water leaves the tank, star

ANEK [815]

Answer:

$9.2\ \text{m}$

Step-by-step explanation:

$b$ = Surface area of base = 5 square meters

Volume of water in tank = 70 cubic meters

The rate at which the volume is reducing is

$\dfrac{dV}{dt}=2+4t\\\Rightarrow dV=2+4tdt$

Integrating from $t=0$ to $t=3$

$V=\int^3_0(2+4t)dt\\\Rightarrow V=2t+2t^2|_0^3\\\Rightarrow V=2\times 3+2\times 3^2-0\\\Rightarrow V=24$

Volume of water remaining in the tank is $70-24=46\ \text{m}^3$

Suface area of base $\times$ depth = Volume

$5\times d=46\\\Rightarrow d=\dfrac{46}{5}\\\Rightarrow d=9.2\ \text{m}$

The depth of the water remaining in the tank is $9.2\ \text{m}$ .

A worker on the production line is paid a base salary of $230.00 per week plus $0.78 for each unit produced. Write an equation

iogann1982 [59]

(a)

We are given

A worker on the production line is paid a base salary of $230.00 per week

so, base salary =230

Let's assume number pencils produced as x

plus $0.78 for each unit produced

now, we can find equation for earnings

$E(x)=230+0.78x$

now, we are given

her earnings of $446.84 for a week when she produced x units

so, we can set E(x)=446.84

and then we can solve for x

$446.84=230+0.78x$

$230\cdot \:100+0.78x\cdot \:100=446.84\cdot \:100$

$23000+78x=44684$

$23000+78x-23000=44684-23000$

$78x=21684$

$\frac{78x}{78}=\frac{21684}{78}$

$x=278$

so, number of pencils = 278........Answer

(b)

If the worker had produced twice that number of units

so, number of pencils =2*278=556

now, we can find earnings

$E(x)=230+0.78x$

now, we can plug x=556

$E(556)=230+0.78*556$

$E(556)=663.68$ .................Answer

Find an equation of the line with the slope m=6 that passes through the point (4,4). Write the equation in the form Ax + By = C

Ainat [17]

Answer:

Y - 6x = - 20

Step-by-step explanation:

Y = 6x + c

Substituting the value of x and y

4 = 24 + c

Subtracting 24 from both sides

C = - 20

Y = 6x - 20

Subtracting 6x from both sides

Y - 6x =- 20
