Duo makes 65% percent of his dumplings with vegetarian fillings. What fraction of Duo's dumplings have vegetarian fillings?

iren2701 [21]

Per cent means for every hundred, so we just put 65 into a fraction with 100. However, percents are already out of 100. So for every 100 dumplings, 65 are vegetarian.

Carmine buys a canoe priced at $478. He pays a total, including tax, of $509.07. What was the tax rate?

Reptile [31]

Answer:

6.5%

Step-by-step explanation:

You can find the tax rate by finding the percentage that the initial price increased by.

First, subtract the initial price from the price after taxes.

509.07 - 478 = 31.07

Knowing this we can find the tax rate using an equation like this.

$\frac{Difference Between Values}{Initial Value} = \frac{x}{100}$

Now we substitute in our values.

$\frac{31.07}{478} = \frac{x}{100}$

With X being the tax rate, we cross multiply both fractions.

3107 = 478x

From here, we solve for x by dividing 3107 by 478.

x = 6.5

Therefore the tax rate is 6.5 percent.

(Note that when you are trying to find the tax rate that you divide by the initial price before taxes to get the correct value.)
