*At first a price was decreased by 12%, then it was discounted again by an additional 5%. What is the percent of the total disco
ratelena [41]

The percent of total discount is 16.4 %

<em><u>Solution:</u></em>

Given that,

<em><u>At first a price was decreased by 12%, then it was discounted again by an additional 5 %</u></em>

To find: Percent of total discount

Let "x" be the original price

<em><u>At first a price was decreased by 12%</u></em>

Therefore,

Discounted price = original price - 12 % of original price

Discounted price = x - 12 % of x

Discounted\ price = x - \frac{12}{100} \times x\\\\Discounted\ price = x - 0.12x\\\\Discounted\ price = 0.88x

<em><u>It was discounted again by an additional 5%</u></em>

Therefore,

Discounted price = 0.88x - 5 % of 0.88x

Discounted\ price = 0.88x - \frac{5}{100} \times 0.88x\\\\Discounted\ price = 0.88x - 0.05 \times 0.88x\\\\Discounted\ price = 0.88x - 0.044x\\\\Discounted\ price = 0.836

<em><u>Thus the percent of total discount is:</u></em>

Percent = 100 \% - 0.836 \times 100 \%\\\\Percent = 100 \% - 83.6 \%\\\\Percent = 16.4 \%

Thus the percent of total discount is 16.4 %

Noah is growing three different types of trees. He is keeping track of the height of each tree over time.
taurus [48]

Answer:

Tree 3

Step-by-step explanation:

The equation for the height of tree 1 is given as:

h = 3.5m

The equation for the height of tree 2 is gotten using the points from the table (2,5) and (4, 10)

Hence:

h-h_1=\frac{h_2-h_1}{m_2-m_1}(m-m_1)\\\\h-5=\frac{10-5}{4-2} (m-2)\\\\h-5=2.5m-5\\\\h=2.5m \\

From the graph of tree 3, we get the points (2,4) and (4, 8)

Hence:

h-h_1=\frac{h_2-h_1}{m_2-m_1}(m-m_1)\\\\h-4=\frac{8-4}{4-2} (m-2)\\\\h-4=2m-4\\\\h=2m \\

Therefore tree 3 grows the slowest
