Ms. Smith had 70 stickers to give to students. She gave 3 to each student and still had 5 left. How many students were there? Write an equation to find the number of students who got stickers. Your answer should be an equation, not a number. *

Step-by-step explanation:

Given:

Total number of stickers

Number of stickers given to each student

To find: an equation to find the number of students who got stickers\

Solution:

Let denotes number of students.

So,

Number of stickers given to students

Stickers left

Total number of stickers

Therefore,

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

i think the amount would be $140.62
