Answer:
$67.20
Step-by-step explanation:
We need to find out how much 1% costs so we can multiply that cost by 12 because it goes up 12%.
60/100=0.6
0.6*12=7.2
Now that we have the markup amount we add it to the actual price of $60 so
60+7.2=$60.20
In order to solve for 'x', we have to use trigonometry
(Bear with me, it's not that bad)
Always remember "SOH CAH TOA." This'll definitely help you figure out when you should use sin (), cosine(), or tangent().
In this scenario, we could use cos(57) but using sin(33) is way easier and more practical.
sin(33) =
Recall that sin is opposite/hypotenuse.
Whip out your calculator and find the value of sin(33)
(A side note: If you're going to use the internet as a calculator, be sure to include "deg" at the end of your equation so that it solves correctly. In this case, type in "sin33 deg." This ensures that the calculator isn't solving your equation in radians, which is the default.)
Anyway:
0.5446 =
Cross multiply:
0.5446x = 7.9
To isolate x, divide both sides by 0.5446:
x =
Whip out your fancy calculator one more time (unless you have the willpower to solve this by hand, I don't)
<u>x = 14.5061</u>
Huzzah! We're finally done! That wasn't too bad, wasn't it?
Note that all of my calculations are rounded, if you needed a specific number of significant figures, tell me and I'll fix it :)
Good luck!
We want to study the profit function for the given case.
We will see that the independent variable is the number of pizzas sold and the dependent variable is the profit.
We know that:
- Each pizza kit is sold for $6.00
- The total cost for the event is $50.
So if the kids sell n of the pizza kits, the revenue is:
r(n) = n*$6.00
The profit is computed as the difference between the revenue and the cost, so the profit equation is:
p(n) = n*$6.00 - $50
Now we want to see:
Which is the independent variable?
The one that is free to change, in this case, is n, the number of pizzas sold.
What is the dependent variable?
The one that changes in response to the changes in the independent variable, in this case, is the profit, obviously, the profit will depend on the number of pizzas sold.
