To find the total profit, add p(x) and q(x):
(110 + 25x) + (15x + 85)
15x + 25x + 110 + 85 --> group like terms
40x + 195 --> add like terms
p(x) + q(x) = 40x + 195 --> This is the function that represents the total profit for January and February
Answer:
$45000
Step-by-step explanation:
Given data
Net income =$50,400
Let the prior year income be x
12/100*x +x= 50400
0.12x+x= 50400
1.12x= 50400
x= 50400/1.12
x= $45000
Hence the prior year income is $45000
Right, so that means starting from 100000 and ending at 999999
how many numbers is that?
999999-100000=899999
but how many of them are odd?
let's take a smaller sample
start with an even and end with odd
from 2 to 7
that is 5 number difference, but the odd numbers are 3 and 5 and 7, so 3 of them
so it seems that for a n number difference when start with even and end with odd, you have (n+1)/2 odd numbers
so
899999 number differnce
(899999+1)/2=900000/2=450000 odd numbers
