Answer:
H(11)=101
Step-by-step explanation:
The function we have is:

and we need to find the value of

this is evaluating the function
when the value of t is 
So, first we substitute
in H(t):

we solve the expression:

the answer is that when
, the function has the value 
Let the price of the 3rd card be c. Now we can write the equation:
c + (c + 20) + (c + c + 20) = 160 .........(1)
Simplifying the left hand side of equation (1), we get:
4c + 40 = 160 .........(2)
Subtracting 40 from both sides of equation (2) gives:
4c = 120
from which c = $30.
Therefore the price of the second card = 30 + 20 = $50
and the price of the first card = 30 + 50 = $80.
