Asixth grade class of 295 students is having an end of the year laser tag party. the party will cost

$8.95 per student, but since so many students are attending the laser tag company is giving the

group a $400 discount. estimate the total cost of the party.

a. $3,100 c. $2,700

b. $2,000 d. $2,300

The total cost of the party is approximately $2300, hence the correct answer is option D.

Step-by-step explanation:

Given:

Number of students = 295 students

cost per student =  $8.95

Discounts given by the company = $400

To find:

We need to estimate the total cost of the party.  

Solution:

To find the total cost of the party we need to multiply the total number of students into the cost per student.

This can be done as follows:

=295×8.95

=2640.25

Therefore, the total cost of the party is $2640.25, but it is given that the laser tag company gave the students a discount of $400. Hence the total cost after discount is  

=2640.25-400

=2240.25

Therefore, the total cost of the party is approximately $2300

Hence the correct answer is option D.

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
