Last month, you were able to purchase 8 computers. By the middle of the current month, you were able to purchase 8 more computer

Arada [10]

Answer:

125 %

Step-by-step explanation:

Computers purchased in the last month = 8

By the middle of the current month, 8 more computers than the last month were purchased. This means, total number of computers purchased by middle of current month = 8 + 8 = 16

Number of computers purchased by end of current month = 2

So,

Total computers purchased by current month = 16 + 2 = 18

We have to find the percentage increase in the number of computers from last month's purchases to the end of this month's purchases. The formula for percentage change is:

$\text{Percentage Change}=\frac{\text{New Value - Original Value}}{\text{Original Value}} \times 100\%$

Here, Original Value is the number of computers from last month and New Value is the number of computers from current month. Using the values in the formula, we get:

$\text{Percentage Change}=\frac{18-8}{8} \times 100\% = 125\%$

Thus, there was a 125% increase from last month's purchases to the end of this month's purchases

The scale for a scale drawing is 8 millimeters: 1 centimeter. Which is larger,the actual object or the scale drawing?explain

amm1812

The scale is a representation of what the drawing is to real life. The drawing will tend to be represented by a fixed figure such as 1 cm. In this case for every cm of drawing it is a representation of 8 millimetres in real life, therefore the drawing is bigger than the object.
