Given:
Function y = 119.67(0.61)x
x = week 3.
F(3) = 119.67(0.61)(3)
F(3) = 119.67*1.83
F(3) = 218.9961
x = week 5
F(5) = 119.67(0.61)(5)
F(5) = 119.67 * 3.05
F(5) = 364.9935
Answer:
92
Step-by-step explanation:

Answer:
The co-efficient of q in sum of the given expression is 2
Step-by-step explanation:
Given expressions are 
and 
Now sum the given expression
Here the co-efficient q is 2 (since
)
The table is:
Number of washes denoted by x: 0, 8, 12
Amount left on card denoted by y: 30, 18, 12
a. Write an equation that shows the amount of dollars left on the card
Solution:
18 – 30 divided by 8 – 0 = -12/8
On simplest form is -3/2
The equation is y = -3/2x + 30
b. Explain the meaning of the negative slope above.
As the number of car washes increase, the dollars left on the card decreases.
c. What is the maximum value of x?
0 = -3/2x + 30
2/3 x 3/2 x = 30/1 x 2/3
Cancel 2/3 x 3/2 and reduce 30 by 3 we get 10, 10 x 2
x = 20
