is that enough to pay the $1100?

now, let's write 1000(1+r)² in standard form

1000( 1² + 2r + r²)

1000(1 + 2r + r²)

1000 + 2000r + 1000r²

1000r² + 2000r + 1000 <---- standard form.

at a party at the middle school over on third avenue next to the bank, $60\%$ of the students are seventh graders. these student

Vaselesa [24]

There are 600 students including the seventh and eighth graders at the party.

This problem uses the concept of percentages to define the conditions that are laid in front of us.

Let the original number of students be S , and the number of seventh graders be = 0.60S

We know that percent is used to convey the mathematical term of a fraction multiplied by 100.

Total students after 20 eighth graders arrive = S + 20

And we have that

Number of seventh graders / total number of students = 58%

.60S / [ S + 20 ] = .58 we multiply both sides by S + 20

0.60S =0 .58 [ S + 20]

.60S = .58S + 11.6 we subtract 0.58S from both the sides

0.02S = 11.6 we divide both the sides by .02

S = 11/6 / 0.02 = 580

So the total number of students = 580 + 20 = 600 .

Hence there are 600 students at the party at that time.
