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 230 = 60 dollars
Let Lena tutors for 3 hours, then the earning = 30+30 +30 OR 330 = 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>

from; f(2)=3
f(2n) nf(2)
(3)(n)
therefore :
f(32)=f(2.16)
f(32)=16f(2)
f(32)=(16)(3)
f(32)=48 final answer
