X= # of people who attended the movie
Numerator= # of people under 30
Denominator= total # of people
60/100 = 1200/x
Then we cross multiply
60x = 120000
x = 2,000
Final answer= 2,000 people attended the theater

Answer:

$570
Step-by-step explanation:
Given that:
For each hour of tutoring, Lena earns 30 dollars.
E is her earning and
H is the number of hours for which she tutors.
To find:
Equation relating E to H.
Solution:
Let Lena tutors for 1 hour, then the earning = 30 dollars
Let Lena tutors for 2 hours, then the earning = 30+30 OR 2
30 = 60 dollars
Let Lena tutors for 3 hours, then the earning = 30+30 +30 OR 3
30 = 90 dollars
If Lena tutors for H number of hours, then the earning, E = 30 + 30 + .... + 30 (H times) i.e.

So, the equation that relates E to H is given as:

Now, it is given that she tutors for 19 hours.
Let us put H = 19 hours in the above equation:

Therefore, the earning for 19 hours of tutoring is <em>570 Dollars.</em>
