Answer:

1.3

Step-by-step explanation:

[tex]\frac{14100-13920}{14100} \times 100 \approx 1.3[/tex]

Answer:

128.52

Step-by-step explanation:

140 × (1-0.15) = 119

119 × 1.08 = 128.52

Answer:

$128.52

Step-by-step explanation:

Firstly to find the price of the scooter, you divide 140 by 100 and then multiply it by 15. The answer is what you subtract from the original price.

15(140/100) = 21

140 - 21 = 119

Now that we have the price of the scooter after the discount, we need to figure out the price of the sales tax. Sales tax is based on the reduced price, so we need to take the same steps as before to find the price. Divide 119 by 100, then multiply it by 8, then add the total to 119.

8(119/100) = 9.52

119 + 9.52 = 128.52

Answer = $128.52

Answer:

180

Step-by-step explanation:

Nightly cost = x

x × 5% = Sales Tax

Total Cost : Percentage

      189     :        105%

         x       :        100%

Cross multiply:

189 × 100% = 105% × x

189 = 1.05x

189 ÷ 1.05 = x

x = 180

Answer:

x = 0

Step-by-step explanation:

Given equation,

→ 2(3x - 1) + 2(4x + 5) = 8

Now the value of x will be,

→ 2(3x - 1) + 2(4x + 5) = 8

→ 6x - 2 + 8x + 10 = 8

→ 14x + 8 = 8

→ 14x = 8 - 8

→ x = 0/14

→ [ x = 0 ]

Hence, the value of x is 0.

The increase in the money supply that causes prices to rise and leads to inflation, loses purchasing power.

What is inflation?

Inflation refers to the persistent rise in the general prices of commodities in the economy over a period of time. If the prices of goods and services increase in an economy without an increase in income of people, it reduces the purchasing power of individuals.

This follows the law of demand which states that; the higher the price, the lower the quantity demanded; the lower the price, the higher the quantity demanded.

Step-by-step explanation:

Option D 26/43 .

Given equation 2/43=t/13

To solve these type of question we have to follow some steps

that are as follows

Multiply all terms by the same value to eliminate fraction denominators

same value is 559 ....so multiply with 559 both sides

2/43=t/13

559×2/43 = 559×t/13 (by multiplying in LHS and RHS with same value)

Cancel multiplied terms that are in the denominator

13 ×2=43t

Multiply the numbers

26=43t

Divide both sides by the same factor

26/43=43t/43

Simplify

Cancel terms that are in both the numerator and denominator

Move the variable to the left

t=26/43 is the answer.

Table C has a constant proportionality between y and x of 0.3.

A constant is an expression-unchanging value or number. It always has the same value.

In mathematics, proportionality denotes a linear relationship between two quantities or variables. Both quantities increase in size when one double, and both decrease in size when one drops to a tenth of its original value.

The answer is the same as the one in the y column when you multiply the x number in table C by 0.3. The value that remains constant in the ratio is the proportionality constant. It is evident that table C is accurate because when you multiply each value in the x column by 0.3, the result is always the value in the y column.
