CaHeK987 [17]

Answer:

$c = 4.211\cdot n$

Step-by-step explanation:

The linear equation has the following form:

$c = \frac{\Delta C}{\Delta n} \cdot n$

Where:

$n$ - Number of MBs of the data plan.

$c$ - Monthly cost of the data plan.

The slope of the function is:

$\frac{\Delta C}{\Delta n} = \frac{c}{n}$

$\frac{\Delta C}{\Delta n} = \frac{80\,MB}{19\,USD}$

$\frac{\Delta C}{\Delta n} = 4.211\,\frac{MB}{USD}$

The equation is:

$c = 4.211\cdot n$

Carys is checking her tax bill for the last year .the tax rates were as follows: no tax on the first 11000 of earnings .earnings

faust18 [17]

Answer:

$7,440.

Step-by-step explanation:

We have been given the tax rates as follows:

$0-$11,000 = No tax.

$11,000-$43,000 = 20%.

$43,000-$150,000 = 40%.

Earnings over $150,000 = 45%.

Since last year Carys earned $45,600, so we will have to find the tax paid by her for 11,000-43,000 at rate of 20%, then the tax for amount over 43,000 at the rate of 40%.

$\text{The amount of tax paid by Carys for 11000-43000}=\frac{20}{100}\times (43,000-11,000)$

$\text{The amount of tax paid by Carys for 11000-43000}=0.20\times (32,000)$

$\text{The amount of tax paid by Carys for 11000-43000}=6400$

$\text{The amount of tax paid by Carys for the amount over 43000}=\frac{40}{100}\times (45,600-43,000)$

$\text{The amount of tax paid by Carys for the amount over 43000}=0.40\times (2600)$

$\text{The amount of tax paid by Carys for the amount over 43000}=1040$

$\text{The total amount of tax paid by Carys}=6400+1040$

$\text{The total amount of tax paid by Carys}=7440$

Therefore, Carys paid an amount of $7,440 in tax.
