Answer:
20 students
Step-by-step explanation:
If the class decreased by 15%, the students that she has now (17) represents a percentaje of:
100% - 15% = 85%
so<u> the 17 students are 85% of what she had</u>:
Students Percentage
17 ⇒ 85%
and we are looking for how many students she had 2 years ago, thus we are looking for the <u>100%</u> of students (the original number of studens). If we represent this number by x:
Students Percentage
17 ⇒ 85%
x ⇒ 100%
and we solve this problem using the <u>rule of three</u>: multiply the cross quantities on the table( 17 and 100) and then divide by the remaining amount (85):
x = 17*100/85
x = 1700/85
x=20
2 years ago she had 20 students
Answer:
The classes need to raise $164.86 more to reach their goal of $1200.
Step-by-step explanation:
$1,200 total
Mrs. LeBlanc's class has raised 50% of the total, so they've raised $600.
1200/2 = 600
Mr. Patel's class has raised $235.14.
235.14 + 600 = 835.14
Ms. Warner's class has raised 1/3 of the total of Mrs. LeBlanc's class ($600), so they've raised $200.
600/3 = 200
835.14 + 200 = 1035.14
The three classes have raised a combined total of $1035.14.
1200 - 1035.14 = 164.86
The classes need to raise $164.86 more to reach their goal of $1200.

Step-by-step explanation:
It's ok! This is simple. Simply plug in your given values. Since g(x) = -1, plug that into the equation.
g(x) = -x + 3
g(-1) = -(-1) + 3
=1+3
=4
