Step-by-step explanation:
Answer:
If the price is p and the cost is c, then
15p = 20c
p/c = 20/15 = 1.333
so, he made 33% profit
First, we need to calculate how much money is the discount. We do that by multiplying 20% with 65$ = 20% * 65$ = 0,2 * 65$ = 13$
When we know how much money is the discount, we will subtract it from original value, and we will get the sale price of the tennis racket :
65$ - 13$ = 52$
Answer:
The answer should be -124.
Given:
The characteristic of an exponential parent function in the options.
To find:
Which is not a characteristic of an exponential parent function?
Solution:
The exponential parent function is:
Where, .
At ,
It means the function passes through the point (0,1) but it does not passes through the origin. So, the statement in option A is true but the statement in option C is false.
The domain of the exponential parent function is all real numbers and the range is positive real numbers (y > 0). So, the statements in the options B and D are true.
Therefore, the correct option is C.
