49.99+34.95+19.99=104.93. 104.93*.0825=8.66, 104.93+8.66=113.59

$113.59 is the total cost with tax.

Hello!

Let's do this step by step.

First, add up the costs of the Xbox, controller, and the walk through manual.

49.99 + 34.95 + 19.99 = 104.93

The total cost of the three items (not including tax) is $104.93.

Sales tax is a tax paid on goods and services, which means it would be added onto the purchase.

To calculate the sales tax, convert the percentage of tax to a decimal, and then multiply the cost of the goods by the decimal, and finally add the two together.

8.25% ÷ 100 = 0.0825

104.93 × 0.0825 = 8.656725

Add the tax to the cost of the items:

104.93 + 8.656725 = 113.586725

This can be rounded to 113.6 to the nearest tenth.

ANSWER:

The cost of James' total purchase will be $113.6.

PSEG Long Island charges its residential customers a little monthly service charge plus an energy charge based on the amount of
german

Using linear function concepts, it is found that:

  • a) It costs $0.1 for each kilowatt hour of electricity used in excess of 250 kWh.
  • b) f(90) = 46.6, which is the cost of 340 kWh of consumption in a month.

------------------------------

A <em>linear function </em>has the format given by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0.

The equation for the cost of h kilowatt hours (kWh) of electricity used in excess of 250 kWh is of:

C = f(h) = 37.6 + 0.1h

Item a:

  • The slope is of m = 0.1, which means that it costs $0.1 for each kilowatt hour of electricity used in excess of 250 kWh.

Item b:

f(90) = 37.6 + 0.1(90) = 37.6 + 9 = 46.6

250 + 90 = 340.

f(90) = 46.6, which is the cost of 340 kWh of consumption in a month.

Answer:

  2444

Step-by-step explanation:

The total cost is the integral of the marginal cost.

  \displaystyle C=\int_{144}^{625}{\dfrac{94}{\sqrt{x}}}\,dx=\left. 2\cdot 94\sqrt{x}\right|_{144}^{625}=188(25 -12)=\boxed{2444}

The total cost of producing units 144 through 625 is 2444.
