13,900 its that because when you multiply you get 13,848 and you look at the number all the way at the end and its 8 and 8 tells you to round up and then when you round you get 13,000

Mrs. Lay's Instagram followers went from 40 to 72. What was the percent increase?

anastassius [24]

Answer:

The percentage increase when Mrs.Lay’s instagram followers went from 40 to 72 is 80%

Solution:

The percentage increase can be found out by dividing change in value by initial value. This is given as,

$\bold{\text { percentage increase } = \frac{( \text {final count-initial count} }{\text {initial count}} \times 100}$

From question, we get

Initial count of Mrs.Lay = 40

Final value of Mrs.Lay = 72

So percentage increase when Mrs Lay’s Instagram followers went from 40 to 72 is

$\text { percentage increase }=\frac{72-40}{40} \times 100$ $= \frac{32}{40} \times 100$

$=\frac{4}{5} \times 100$

= 80

Hence percentage increase when Mrs Lay’s Instagram followers went from 40 to 72 is 80%.

Select the correct answer from each drop-down menu. A self-service car wash charges $4 for the initial 5 minutes plus an additio

arlik [135]

Answer: For $m\geq15$

$\\\Rightarrow\ y=4+0.75(m-5)\geq4+0.75(15-5)\\\Rightarrow\ y\geq4+0.75(10)\\\Rightarrow\ y\geq4+7.5\\\Rightarrow\ y\geq11.5$

Nick does not has enough money to follow this recommendation.

Step-by-step explanation:

Given: A self-service car wash charges $4 for the initial 5 minutes plus an additional $0.75 for each minute after that.

Let y be the cost for car wash for m minutes then

$y=4+0.75(m-5)$ such that at m= 5 , y=4 which is the cost for car wash (dollars) for first 5 minutes.

Also, A car enthusiast magazine recommends spending at least 15 minutes to properly wash a car.

For $m\geq15$

$\\\Rightarrow\ y=4+0.75(m-5)\geq4+0.75(15-5)\\\Rightarrow\ y\geq4+0.75(10)\\\Rightarrow\ y\geq4+7.5\\\Rightarrow\ y\geq11.5$

But Nick has $10 which is less than $11.5, so he does not has enough money to follow this recommendation.
