A group of students planned to chip in to raise a total of $100 for one of their friends’ birthday party but 5 persons couldn’t come so they didn’t pay. This increased the share of the others by $1 each. Find the amount that each person paid after

$5

Step-by-step explanation:

Let the number of students be x, then

Initial amount per student was:

After it becomes:

Since amount increased after, it can be shown as:

Multiply each term by x(x - 5) to get rid of the fraction:

Positive solution of this quadratic equation is

Amount each person paid after:

mk./km: lm

step-by-step explanation:

,mlmlm

; mk

lk

option b  

step-by-step explanation:

we know that

the distance from point n to lm in the figure is equal to the distance of the perpendicular line to lm that passes through the point n

so

the distance is equal to the segment no

> given problem

therefore

the distance from point n to lm is equal to
