Mrs. Smith donated $20
The constant proportionality is $1 because no matter what, Mrs. smith will donate $1 for each mile. So if Sam were to only walk 1 mile, mrs. smith would donate $1. Or seen as a 1:1 proportion.
Answer: The three consecutive odd integers are: -15, -13, and -11 .

Explanation:
_____________________________________________
x + (x + 2) + (x + 4) = -39 ;
_____________________________________________
in which "x" is one of the integers,
"(x + 2)" is the next consecutive odd integer;
"(x + 4)" is the third consecutive odd integer.
__________________________________________
By solving for "x", we can solve for each of three (3) consecutive odd integers.
________________________________________________________
x + (x + 2) + (x + 4) = -39 ;
_________________________________________________________
1x + 1x + 2 + 1x+ 4 = -39 ;
_____________________________________________________
3x + 6 = -39 ;
______________________________________________
Subtract "6" from EACH side of the equation:
______________________________________________
3x + 6 − 6 = -39 <span>− 6 ;
____________________________________________________
to get: 3x = -45 ;
____________________________________________________
Divide EACH side of the equation by "3" ;
____________________________________________________
3x / 3 = -45 / 3 ;
_____________________________________________________
to get: x = -15 ;
______________________________________________________
x + 2 = -15 + 2 = -13 ;
_______________________________________________________
x + 4 = -15 + 4 = -11 .
___________________________________________________
Are: -15, -13, and -11 ; Consecutive odd integers? YES!
___________________________________________________
Does: -15 + (-13) + (-11) =? = -39 ??
_____________________________________________________
-15 </span>− 13 <span>− 11 = ? 39 ?? YES!
____________________________________________________
Answer: The three consecutive odd integers are: -15, -13, and -11.

Given:
Last month sales = $900
Rate of commission = 20%
To find:
How much commission (in dollars) did she earn last month?
Solution:
We have, 20% rate of commission. So, the commission for the last month is equal to 20% of last month sales $900.



Therefore, the commission for the last month is $180.
