Zack wants to make a profit of more than $300 for painting 4 identical rooms. The profit he makes is equal to the amount he is paid minus the cost of supplies. The cost of supplies is$32.50 for each room. Which inequality and solution represent the dollar amount, n, that Zack must be paid for each room, if he is to make a profit of more than $300?

A) n-4(32.5)>300;n>430
B) 4(n-32.5)>1,200;n>332.5
C) 4n-32.5>300;n>83.125
D) 4(n-32.5>300;n>107.5

PLZ ANSWER WILL BE MARKED BRAINLIEST

n-4(32.5) > 300;n > 430tep-by-step explanation:

Zack wants to make a profit of more than $300 for painting 4 identical rooms. That is

Profit > $300

the profit he makes is equal to the amount he is paid - the cost of supplies. The cost of supplies is $32.50 for each room. That is

n - 32.5 and

P + 32.5 × 4

Where 4 = number of rooms

P + 130

n-4(32.5) > 300;n > 430tep-by-step explanation:

given that Zack wants to make a profit of more than $300 for painting 4 identical rooms. That is

Profit > $300

Then, the profit he makes is equal to the amount he is paid minus the cost of supplies. The cost of supplies is $32.50 for each room. That is

n - 32.5 and

P + 32.5 × 4

Where 4 = number of rooms

P + 130

The minimum profit = 300 + 130 = $430

n-4(32.5) > 300;n > 430 430

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
