Answer:
The ratio is 4/11
Step-by-step explanation:
Let
x ----> the total number of students in a school
we know that
1) 2/3 of the students study a language.
so
(2/3)x ----> number of students studying a language
and
x-(2/3)x=(1/3)x ---->number of students who do not study a language
2) Of those who study a language 2/5 were studying french
so
(2/3)x(2/5)=(4/15)x ----> number of students studying French
and
(2/3)x(3/5)=(6/15)x ----> number of students studying a language but not studying French
3) we know that
The number of students who do not study French is equal to the number of students who do not study a language plus the number of students who study a language but do not study French.
(1/3)x+(6/15)x=(11/15)x ----> number of students who not study French
(4/15)x ----> number of students who study French
4 ) Find the ratio of students who study french and who do not
(4/15)x/(11/15)x=4/11
So here, we are starting with two numbers: the original price, and the price after the percent increase.
First, we need to find the differences between the prices to figure out how much of a difference the percent made. $181.09 - $102.30 = $78.79
$78.79 is how much money the original price was increased by. We can find the percent change using this, since this number is what percent of the original price went up.
So now: $78.78 / $102.30 = .77018
And now, we convert that to percent: 77%
The markup was 77%.
Answer:
So, if it grows by 6.75%, each year the population is 106.75% of the year before.
After 1 year, 370,000(1.0675). After two years, 370,000(1.0675)(1.0675).
370,000(1.0675)12 = your answer
Step-by-step explanation:
