Answer:
Selling price of hockey game set is $145.32 , markup price is $210.54 and profit is $96 .
Step-by-step explanation:
Let us assume that the selling price of hockey game set be x .
As given
Pyotr Tchaikovsky Sporting Goods operates on a 45% overhead based on the selling price, which results in an overhead of $65.34 on the newest version of an air hockey game set.
45% is written in the decimal form .

= 0.45
Thus the equation becomes
0.45 × x = 65.34
0.45x = 65.34

x = 145.2
Therefore the selling price of the hockey game set is $145.2 .
Thus
Markup price = Selling price + Overhead Price
= $145.2 + $65.34
= $ 210.54
As given
If the air hockey game set costs Pyotr Tchaikovsky Sports $49.32 .
i.e Cost price of the hockey game set = $ 49.32
Profit = Selling price - Cost price
= 145.32 - 49.32
= $ 96
Therefore selling price of hockey game set is $145.32 , markup price is $210.54 and profit is $96 .
Answer:
h(x) = 0.0045x – 0.4
Step-by-step explanation:
The length of time in hours of two airplane flights are represented by the following functions, where x is the number of miles for the flight.
Flight A: f(x) = 0.003x - 1.2
Flight B: g(x) = 0.0015x + 0.8
Then the function
h(x) = f(x) + g(x) = (0.003 + 0.0015)x + (-1.2 + 0.8) = 0.0045x - 0.4.
Therefore, the third option is the right option. (Answer)
