Calculate 6¾% tax on $2,305 a.$15.56 b.$145,22 c.$146,14 d.$155,59.

Hello! 6 3/4 is equivalent to 6.75. So basically, you would be paying 6.75% tax. To find the amount of tax, multiply the price by the percentage rate. 2,305 * 6.75% (0.0675) is 155.5875 or 155.59 when rounded to the nearest hundredth. You would pay $155.59 in tax. The answer is D.

Using the given points and line, determine the slope of the line. (-3,0) and (2,7)

o-na [289]

Answer:

slope = $\frac{7}{5}$

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 3, 0) and (x₂, y₂ ) = (2, 7)

m = $\frac{7-0}{2+3}$ = $\frac{7}{5}$

A man earns 12,000 per year, 10% of it was spent on transport while 5% of the salary went as tax. He spent 80% of the remainder

weqwewe [10]

Answer:

Amount left = 2040

Step-by-step explanation:

Given that:

Per year salary = 12,000

Amount spent on transport = 10%

Transport = $\frac{10}{100}*12000$ = 0.1 * 12000

Transport = 1200

Tax = 5%

Tax = 0.05 * 12000

Tax = 600

Total = 1200 + 600 = 1800

Amount left = 12000 - 1800 = 10200

Food = 80% of remainder

Food = 0.8 * 10200

Food = 8160

Amount left after food = 10200 - 8160 = 2040

Hence,

Amount left = 2040
