$\bf \cfrac{7y-x}{z}~~ \begin{cases} x=9\\ y=5\\ z=4 \end{cases}\implies \cfrac{7(5)-9}{4}\implies \cfrac{35-9}{4}\implies \cfrac{26}{4}\implies \cfrac{13}{2}\implies 6\frac{1}{2}$

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:

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