Two key parts of this solution.
<u>1) </u><u /><u>Set up the right equations.</u> Let's say that x is the number of hours during the weekdays, and y is the number of weekend hours. In each week, Ramiro will earn $20*x for his work on weekdays and $30*y for his work on weekends. The second sentence tells us that in this week, the total is $650. So, our first equation is:
20x + 30y = 650
The third sentence tells us that x is 5 times as many hours as y. In other words:
x = 5y
<u>2) Solve for one of the variables.</u><u /> Now that you have 2 equations with 2 variables, you can manipulate the equations to cancel out one variable and solve for the other. Since the question asks for the number of weekend hours, let's solve for y.
Here, it's easier to just substitute x in the original equation. If you put 5y in place of x, the equation becomes:
(20*5y) + 30y = 650
expand -->
100y + 30y = 650
add -->
130y = 650
divide both sides by 10 -->
13y = 65
divide both sides by 13 -->
y = 5
So, Ramiro worked 5 hours on the weekend (and therefore, 25 during the week).
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 .
![= \frac{45}{100}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B45%7D%7B100%7D)
= 0.45
Thus the equation becomes
0.45 × x = 65.34
0.45x = 65.34
![x = \frac{65.34}{0.45}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B65.34%7D%7B0.45%7D)
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 .
