Chase goes out to lunch. The bill, before tax and tip, was $11.90. A sales tax of 9% was added on. Chase tipped 17% on the amoun

WINSTONCH [101]

Answer:

$15.17

Step-by-step explanation:

First we calculate the value for the sales tax:

$11.90 \times \frac{9}{100 } = 1.07$

we then add the value for the sales tax ($1.07) to the initial bill:

$11.90 + 1.07 = 12.97$

We were instructed to calculate the tip after the sales tax was added so:

$12.97 \times \frac{17}{100} = 2.20$

after we will add the value for the tip to the value that we have for the bill ( this is the new value that includes the sales tax) to find the total cost:

$12.97+ 2.20 = 15.17$

Therefore the total cost for his mean is $15.17

Suppose that for a certain company C(x)=35x+300,000 represents the total cost function, and R(x)=75x represents the total rev

enyata [817]

Answer:

40x - 300,000

7,500

Step-by-step explanation:

profit = revenue - cost

p(x) = 75x - (35x + 300,000)

p(x) = 40x - 300,000

Break even is when profit is zero

40x - 300,000 = 0

40x = 300,000

x = 7,500

Find an equation of the plane. the plane through the point (−5, 9, 10) and perpendicular to the line x = 1 + t, y = 4t, z = 2 −

PtichkaEL [24]

The direction vector of the line
L: x=1+t, y=4t, z=2-3t
is <1,4,-3>
which is also the required normal vector of the plane.

Since the plane passes through point (-5,9,10), the required plane is :
Π 1(x-(-5)+4(y-9)-3(z-10)=0
=>
Π x+4y-3z=1
