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%

A calculator may be used for this question.

Lilit [14]

14 x 3/4 = 42/4 = 10.5 lbs
1 lb = 450 g...so 10.5 lbs = (10.5 x 450) = 4725 g.....1 g = 0.001 kg....so 4725 grams = (4725 x .001) = 4.725 kg

so ur gonna need a medium sized turkey.....4.725 kg...at 5.99 per kg =
(4.725 x 5.99) = $ 28.30 <==
