When the new computer lab opened there were 18 computers.by the end of firdt week there were 25 computers. Find the percent of c

aliina [53]

The number of computers increased by 38.9%

Step-by-step explanation:

Number of computers at start of week = Old value = 18

Number of computers by end of week = New value = 25

Change = New value - Old value

Change = 25-18 = +7

The positive sign indicates the increase.

Increase percent = $\frac{Change}{Old\ value}*100$

$Increase\ percent=\frac{7}{18}*100\\\\Increase\ percent=\frac{700}{18}\\\\Increase\ percent= 38.88\%$

Rounding off to nearest tenth

Increase percent = 38.9%

The number of computers increased by 38.9%

Elisa is nearing graduation. She just met with her counselor and he showed her this information.

Arada [10]

Answer: $14,000

Step-by-step explanation:

Given the following :

Room & Board = $11,500

Work - study = $8000

Grant & scholarship = $9500

Tuition fee = $9500

If she pays balance with a student loan, how much will she need to borrow:

Elisha's bill:

Tuition fee and room and board

($9500 + $11500) = $21,000

Elisha's earning:

Work - study and scholarship & grant

($8000 + $9500) = $17500

Therefore,

Amount to borrow per year :

$21,000 - $17,500 = $3500

For four years :

4 × $3,500 = $14,000
