32% of the students take the bus
170 students walk home.
how many students are in the sixth grade?

There are 250 students in sixth grade

Solution:

Given that, All the students in the sixth grade either walk home or take the bus home after school

From given,

Number of students walk home = 170

Let "x" be the total number of students in school

32% of the students take the bus

Thus, 32 % of "x" takes bus

To find: total number of students in school

Total students = Number of students walk home + number of students takes bus

Thus there are 250 students in sixth grade

300

step-by-step explanation:

28-600w < 300

28-600w > 300

600-28w < 300

600-28w > 300

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
