Answer:
Amount of bill after discount = $55.25
Amount of tip left = $13
Total money spent at the restaurant = $68.25
Step-by-step explanation:
Original bill amount of Mr. Hudson = $65
Discount card value = 15% of the bill
Tip offered = 20% of the original amount
To find:
Amount of bill after the discount of 15%.
Amount of tip left.
Total amount spent in the restaurant.
Solution:
Let us apply the percentage here to find the values of total discount, total tip offered.
Discount = 15% of $65
Amount of bill after discount = $65 - $9.75 = $55.25
Amount of tip left = 20% of $65
Total money spent at the restaurant = Amount of bill after discount + tip offered = $55.25 + $13 = <em>$68.25</em>
<em></em>
The answers are:
Amount of bill after discount = $55.25
Amount of tip left = $13
Total money spent at the restaurant = $68.25

Answer:
it depends
Step-by-step explanation:
The ideas of "increasing" or "decreasing" have to do with the sign of the derivative of a function. The derivative of a function is a limit, which is only defined if the point can be approached from both sides. For a function that is only defined on an interval, the derivative is undefined (hence "increasing" or "decreasing" are undefined) at the end points of the interval.
When the function is defined on an interval, "increasing" or "decreasing" can only be determined on that open interval. There may also be critical points within an interval at which the derivative is either zero or undefined. Those points must also be excluded from any interval of "increasing" or "decreasing".
__
If a function is defined over a domain that extends beyond the interval of interest, then the derivative may very wll be defined a the end points of the interval of interest. As a simple example, consider a line with defined non-zero slope: y = kx, k≠0. For k>0, the line will be increasing everywhere. The slope is defined at the end points of any finite interval, so the function can be said to be "increasing" on the closed interval.
Similarly, if the (finite) interval of interest includes the vertex of a parabola defined for all real numbers, the function will be "increasing" on one side of the vertex, and "decreasing" on the other side. Both the "increasing" and "decreasing" intervals will be half-open intervals. The point at the vertex will not be included in either of them.
Answer:
y = 8x + 25
Step-by-step explanation:
Using the coordinates (10, 105) and (20, 185)
The standard linear equation is expressed as y = mx+c
m is the slope
c is the intercept
m = 185 - 105/20-10
m = 80/10
m = 8
Get the y-intercept
Since y = mx+c
105 = 8(10) + c
105 = 80 + c
c = 105 - 80
c = 25
Get the required equation
Recall that y = mx+c
y = 8x + 25
Hence the required equation is y = 8x + 25
Answer:
I am pretty sure $750
Step-by-step explanation:
Since there are 10 slices of cake, you would have to divded the cost ($2,500) by 10 to find out the cost per slice (you would get $250). Since we are finding the cost of 3 slices, you would mulitply 250 by 3, then you get your answer
Answer:
There is no solution to the systems of equation.
Step-by-step explanation:
Graph the system by using y=mx+b
Both systems are y=2/5x+5/2.
