Answer:

G = 1, 9.

Step-by-step explanation:

There are two cases to this problem: G is either to the left or right of E. If G is to the left of E, then G = 5 - 4 = 1 and if G is to the right of E, then G = 5 + 4 = 9. Therefore, our answer is G = 1, 9.

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

x = 280/14

x = 20
