Answer:

The statement is not reasonable.

Step-by-step explanation:

Josefina gave away 130% of her stamp collection.

We cannot give more than what we have.

lets understand it mathematically.

suppose i have x stamp.

according to question, i have to give 130% of my stamp collection

130% of x = 130/100 x = 1.3x

so, i have to given 1.3x stamp while i do have only x stamp which does not make any sense.

maximum i can give is x stamp.

x stamp in percentage of my total stamp collection which is also x will be

= x/x*100 = 100%

Thus, maximum one can give is 100% of what he has.

Thus, we can say that Josefina gave away 130% of her stamp collection is not reasonable.

The sales tax on a $20 hammer is 7 percent, or $1.40. why is this tax a bigger burden for josh, who has a $15,000 income, than f
Bond [772]

Answer:

The ratio of the sales tax to Josh income is greater than the sales tax to aaron income (As the income of the Josh is less as compared to the arron income) this shows the tax is bigger burden for the Josh as compared to the aaron .

Step-by-step explanation:

As given

The sales tax on a $20 hammer is 7 percent, or $1.40.

As income of the  josh is 15000 and the income of the aaron is $150000 .

Now the ratio of the sales tax to the josh income .

\frac{Sales\ tax}{Josh\ income} = \frac{1.40}{15000}

\frac{Sales\ tax}{Josh\ income} = \frac{14}{15000\times 10}

\frac{Sales\ tax}{Josh\ income} = \frac{7}{75000}

In decimal form

\frac{Sales\ tax}{Josh\ income} = 0.000093\ (Approx)

Now the ratio of the  sales tax to the aaron income .

\frac{Sales\ tax}{aaron\ income} = \frac{1.40}{150000}

\frac{Sales\ tax}{aaron\ income} = \frac{14}{150000\times 10}

\frac{Sales\ tax}{aaron\ income} = \frac{7}{750000}

In decimal form

\frac{Sales\ tax}{aaron\ income} = 0.0000093\ (Approx)

Thus as the ratio of the sales tax to Josh income is greater than the sales tax to aaron income (As the income of the Josh is less as compared to the arron income) this shows the tax is bigger burden for the Josh as compared to the aaron .

A bottle contains 255 coins. 1/3 of the coins are ?1.00. 110 of the coins are 50p coins. the rest are 20p coins. work out the to
aliina [53]

Answer:

£152.

Step-by-step explanation:

We have been given that a bottle contains 255 coins. 1/3 of the coins are  £1.00.

Let us find 1/3 of 255 to find the number of £1 coins.

\£1\text{ coins}=\frac{1}{3}\times 255

\£1\text{ coins}=85

This means we have £85.

We are also told that 110 of the coins are 50 p coins.

\text{Value of 50 p coins}=\£0.50\times 110

\text{Value of 50 p coins}=\£55

Let us figure out number of 20 p coins by subtracting the number of £1 coins and 50 p coins from 255.

\text{Number of 20 p coins}=255-(85+110)

\text{Number of 20 p coins}=255-(195)

\text{Number of 20 p coins}=60

\text{Value of 20 p coins}=\£0.20\times 60

\text{Value of 20 p coins}=\£12

Now let us find total value of the coins contained in the bottle by adding the values of £1 coins, 50 p coins and 20 p coins.

\text{The total value of the coins}=\£85+\£55+\£12

\text{The total value of the coins}=\£152

Therefore, the total value of the coins contained in the bottle is £152.
