Alex collected 2,876 golf balls over 8 hours of diving. She collected an equal number of balls every hour. How many golf balls per hour is that? What is the remainder?

Alex collected 359 golf balls each hour and 4 balls were remaining as remainder.

Step-by-step explanation:

Given:

Total golf balls collected =2876

Number of hours = 8 hours.

We need to find the number of golf balls collected in per hour.

And what is the remainder.

Solution:

In 8 hours = 2876 balls collected

1 hour = Number of golf balls collected in 1 hour.

Using Unitary method we get;

Number of golf balls collected in 1 hour =

But given she collects equal number of golf balls in each hour and golf balls cannot be in decimal number.

so we can say that;

Alex collected 359 golf balls each hour and 4 balls were remaining as remainder.

step-by-step explanation:

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
