Answer: 69
Step-by-step explanation:
Let the original employee be x , this means that
116% of x = 80
= 80
116x = 8000
divide through by 116
x = 8000/116
x = 68.96551724
Since we are dealing with employees , therefore x ≈ 69
This means that there were 69 employees originally
<h3>4 times a number increased by 3.</h3>
When we have a number that appears
right before a variable, it means multiplication.
So 4n means the same thing as 4 times a number.
Remember, n is a variable which is just a
letter that represents any number.
Since we are adding 3 to 4n, we can say
4 times a number increased by 3.
So 4n + 3 can be written as 4 times a number increased by 3.
Answer:
852 students walking to school
Step-by-step explanation:
Lets start with a simple example so you can get it
if 60% of 100 students walk to school that means
60 students walk to school... right??
so lets simplify it more that means you have multiplied 100 (students) by 60%
or 
(note: you can say that 60% is equal to )
so the problem told 60% of 1420 students walk to school that means we should

Answer:
4.8 Liters
Step-by-step explanation:
Sundaes at her next birthday party. She thinks each person will eat 200 milliliters of ice cream, and there will be 24 people at her party. How many liters of ice cream should she buy
Step 1
1 person = 200ml of ice cream
24 persons = x
Cross Multiply
x = 24 × 200ml of ice cream
x = 4800 ml of ice cream
Step 2
How many liters of ice cream should she buy
We convert from Milliliters to Liters
1 milliliters= 0.001 liters
4800 millilitres = x
Cross Multiply
= 4800 × 0.001 liters
= 4.8 Liters
Therefore, she should buy 4.8 Liters of ice cream
