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.

The total cost in dollars for Larry to have his birthday party at a local

luda_lava [24]

Answer:

$0 \leq p < 6$

Step-by-step explanation:

Given

$t = 6.95p + 29.95$

$Amount = 70$

Required

Determine the domain

First, we need to solve for p

Substitute 70 for t in $t = 6.95p + 29.95$

$70 = 6.95p + 29.95$

Collect Like Terms

$6.95p = 70 - 29.95$

$6.95p = 40.05$

Solve for p

$p = 40.05/6.95$

$p = 5.76$

This implies that Larry can not invite up to 6 people.

Hence, the domain can be represented as: $0 \leq p < 6$

Please help me asap!! Which of these lines, if any, are parallel or perpendicular?

Over [174]

Lines A and B are parallel. Lines A and B apre perpendicular to Line C.

Change all of the lines from standard form to slope-intercept.

Line A: y = 4/3x + 2/3
Line B: y = 4/3x + 2
Line C: y = -3/4x + 1

Since A and B have the same slope they are parallel. C has a negative reciprocal so it's perpendicular.
