Answer:
-78
Step-by-step explanation:
I'm going to assume that you are asking how a number can have two factors.
So, a factor is an integer (non-fractional/decimal number) you multiply by another integer to get the actual number.
Well, let's look at the number 4. The number four has the following factors:
1, 2, 4
In a 'rainbow' style, you match the two outer numbers, then the two next inner numbers, and so on.
Because the number '2' is the one in the center and there is no other number to multiply it by, it must multiply by itself to reach the number 4.
Well, you must have two numbers to actually multiply together, so every number has two factors: 1, and itself (except for 0).
I hope this helps, and good luck :)
Answer:
Person 3 needs to pay $900.
Step-by-step explanation:
Consider the provided information.
The marginal cost of providing 25 neighborhood street lamps is $2000.
Person 1 is willing to pay $800 for the 25 lamps.
person 2 is willing to pay $300 for the 25 street lamps.
We need to find the minimum amount person 3 is willing to pay for 25 street lamps?
Let person 3 need to pay x amount.
Therefore, the sum of the amount should be equal to $2000.
$2000=$800+$300+x
$2000=$1100+x
x=$2000-$1100
x=$900
Hence, person 3 needs to pay $900.
