A group of students are intending to offer a present to a friend. If each one pays 3000 LL.
on amount of 6000 LL is still needed, while if each one pays 4000 LL, they will collect
2000 LL more. Calculate the number of the students, and the price of the present

There are 8 friends and the presents costs $30,000

Step-by-step explanation:

Let x be the number of students and y be the price of the present. Their contributions can be expressed as:

#Make y the subject in equation i then substitute in ii:

Hence, there are 8 friends and the present is priced at $30,000

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

correct me if i am wrong.
