Answer:

164 respondents answered "yes"

69 respondents answered "yes"

126 respondents answered "yes"

Step-by-step explanation:

Let's take these problems one at a time.

First problem: 195 Juniors and 215 Seniors. 2 out of 5 answered "yes".

Now let's first find the total number of students.

Total Students  = 195 + 215

Total Students = 410

Now 2 out of 5 also means the 2/5 or 40% of the students answered yes.

To see how many said yes, we simple multiply the total number of students to the value of 40% or 0.40.

Total Students that answered "yes" = 410 x 0.40

Total Students that answered "yes" = 164

Second Problem: 125 Juniors and 220 Seniors. 0.80 answered "no".

Same process, we first look for the total number of students.

Total Students = 125 + 220

Total Students = 345

Now 0.80 or 80% of them said "no".

We take the total number of students and multiply the number of students to the value of 80% or 0.80.

Total Students that answered "no" = 345 x 0.80

Total Students that answered "no" = 276

Now to find out how many answered "yes", we subtract the total number of students to the students that said "no".

Total Students that answered "yes" = 345 - 276

Total Students that answered "yes" = 69

Third Problem 200 Juniors and 160 Seniors. 35% answered "yes"

Same process, we first look for the total number of students.

Total Students = 200 + 160

Total Students = 360

To see how many said yes, we simple multiply the total number of students to the value of 35% or 0.35.

Total Students that answered "yes" = 360 x 0.35

Total Students that answered "yes" = 126

What is the total cost of $ 2.95 notebook plus 5 %
nordsb [41]
First, you convert 5% to decimal. For your info, percents are always equal to 100. So, you divide 5 by a 100, which gives you 0.05. Then, you multiply 2.95 by 0.05. 2.95 x 0.05 is 0.1475 which is about 0.15. Then, you add 0.15 to 2.95. The total cost of a $2.95 notebook plus 5% is about $3.10.
