Answer:

$3600 per year into savings

Step-by-step explanation:

He makes 1500 dollars a month

1/5 of that goes into saving

1/5*1500 = 300

300 per month goes into savings

We want to know how much goes into savings per year

There are 12 months in a year, so we need to multiply by 12

300 per month * 12 months/ year = 3600 per year

$3600 per year into savings

On a given day, 36 of the 445 students in a school were absent. What was the appproximate absentee rate that day?

Nata [24]

Answer: The approximate absentee rate that day would be 8.09%.

Step-by-step explanation:

Since we have given that

Number of students who were absent = 36

Total number of students = 445

We need to find the approximate absentee rate that day :

Rate of absentee of that day would be

$\dfrac{\text{Number of absentee}}{\text{Total number of students}}\times 100\\\\=\dfrac{36}{445}\times 100\\\\=8.09\%$

Hence, the approximate absentee rate that day would be 8.09%.
