Answer: 13
Step-by-step explanation:
add 24 to 54 and you get 78. divide that by 9 and you get 13.
24 is the total price off
54 is the total he pays
add 54 and 24 to get 78, the original total without any off
9 is the amount each cup costed with the 4 dollars off
divide 78 by 9
13 would be the answer
13- 9 is also 4 dollars
Answer:
11
Step-by-step explanation:
4+5+7+14+17+12+18=77
Divide your total by the amount of numbers you have (7); 77/7
The inverse of the function is k(x) = 
You can find the inverse of any function by switching the k(x) value and the x value. After that, solve for the new k(x). The result will be your inverse function. The step-by-step process is below.
k(x) = 10x + 5 ----> Switch the x and k(x)
x = 10k(x) + 5 ----> Subtract 5 from both sides
x - 5 = 10k(x) ----> Divide both sides by 10.
= k(x) ----> Now switch the order for formatting
k(x) = 
And this is your new inverse function.
