Answer:
C. 
Step-by-step explanation:
You are given the exponential function 
From the table,
at
thus
![N(0)=a\cdot b^0\\ \\150=a\cdot 1\ [\text{ because }b^0=1]](https://tex.z-dn.net/?f=N%280%29%3Da%5Ccdot%20b%5E0%5C%5C%20%5C%5C150%3Da%5Ccdot%201%5C%20%5B%5Ctext%7B%20because%20%7Db%5E0%3D1%5D)

thus

Since
substitute it into the second equation

and the expression for the exponential function is

Answer: A: He payed 3 dollars in sales tax B: He payed 27.59 for his ticket
Step-by-step explanation:
A: 42.99 + 7% = 45.99 - 42.99 + 3
B: 42.99 - 40% = 24.79 + 7% = 27.59
A the answer is 9.76
B: he paid with 10 dollar bill you have to subtract 10.00-9.76 he received 24 cents back!
A:
Area: 289 m
Perimeter: 51 m
B:
Area: 4 m
Perimeter: 8 m
It would be the fourth choice, 3y.
Remember, to get the product of two numbers, you must multiply them together.
Difference=subtraction
Sum=addition
Quotient=division
