Answer:

$31.80

Step-by-step explanation:

First, find the sale price.

Normally you pay for 100% of the price. Since it is 25% off, you only pay for 75% of the price. (100%-25%=75%)

Therefore, we can multiply 75% and $40

75% * $40

Convert 75% to a decimal by dividing 75 by 100 or moving the decimal place 2 spots to the left.

75/100=0.75

75.0 --> 7.5 --> 0.75

0.75* $40

Multiply

$30

Now, find the price with tax.

You have to pay for 100% of the price, plus an additional 6% for the tax. Therefore, you are actually paying for 106% of the price (100% + 6% = 106%)

Therefore, we can multiply 106% and $30

106% * $30

Convert 106% to a decimal by dividing 106 by 100 or moving the decimal place 2 spots to the left.

106/100=1.06

106.0 --> 10.6 --> 1.06

1.06 * $30

Multiply

$31.8

Niko paid $31.80 for the game.

The population is the entire tea drinking community of a country.

If Zach has 4 times as many dimes as quarters and they have a combined value of 455 cents, how many of each coins does he have?
aliya0001 [1]

<u>ANSWER: </u>

Zach has 28 dimes and 7 quarters.

<u>SOLUTION: </u>

Given, Zach has 4 times as many dimes as quarters  

And they have a combined value of 455 cents,  

We need to find how many of each coins does he have?

Let, the number of dimes be x and number of quarters be y.

Then, x = 4y → (1)

Total combined value = 455 cents

x(value of one dime) + y(value of one quarter) = 455 cents

x(10 cents) + x(25 cents) = 455 cents

10x + 25y = 455 → (2)

Now, substitute (1) in (2)

10(4y) + 25y = 455

40x + 25y = 455

65y = 455

y = 7

substitute y value in (1)

x = 4(7)  = 28

Hence, zach has 28 dimes and 7 quarters.
