Answer:
$204.98
Step-by-step explanation:
Step 1: Add both item cost
Step 2: Find the sales tax of the result
- Step 1: Convert 8% to fraction
- Simplify
- Step 2: Convert 189.80 to a fraction
- Step 3: Set it up
- Step 4: Cross divide
- Step 5: Multiply the result
Step 3: Add the result from the total cost of both items
The total cost of the hats and boots including sales tax is 204.98 dollars
Answer:
-1.5x + 70
Step-by-step explanation:
Total money he takes while going to the fair = $90
Money he spends to enter the fair = $5
Money he spends on food =$15
Total he spent now is given by
Now, he spend on rides at the fair i.e. 1.50 per ride .
Let the number of rides be x
So, cost incurred on rides = 1.5x
So, the spending money can be expressed as
Now, remaining money left to him after spending on x rides too is
Let f(x) denotes the function used to determine the money he has left over after rides .
So it becomes
f(x) = 70 - 1.50x
f (x) = -1.50x +70
This will be easier to write, and a lot easier to read, if we temporarily
use another symbol ... say, 'Q' ... to represent ' sin(2x) ' .
Here we go:
Original equation: Q² - 0.5 Q = 0
Factor the left side: Q (Q - 0.5) = 0
This equation is true if either factor is zero:
-- If Q=0, then sin(2x) = 0
2x = 0°, 180°, 360°
x = 0°, 90°, 180°
-- If (Q-0.5) = 0, then Q = 0.5
sin(2x) = 0.5
2x = 30°, 150°
x = 15°, 75°
The whole collection of solutions
between 0° and 360° :
x = 0°, 15°, 75°, 90°, 180° .
Well we know that:
1-4 stay on the floor,
5-9 it's round up time.
So with that in mind you would round the 9's up and they would round up th 4 to a 5. 5's round up so that would round up the first 4 to a 5.
SO your answer would be 5,000.
