Miranda and Savannah are excited that a new store just opened in town! They go together the first day it opens! Each time Miranda goes to the store she plans to spend $7dollar sign, and each time Savannah goes to the store she plans to spend $9A a few weeks from now, Miranda and Savannah are surprised to find out that they have spent the exact same total amount of money at the store.

Given :

Miranda goes to the store she plans to spend $7dollar sign, and each time Savannah goes to the store she plans to spend $9 sign a few weeks from now.

Miranda and Savannah are surprised to find out that they have spent the exact same total amount of money at the store.

To Find :

Least possible number of times that Miranda has been to the store.

Solution :

It is common to see that :

7 dollar/visit ×9 visits = $63

9 dollar/visit ×7 visits = $63

Therefore, minimum number of times Miranda has been to the store is 9.

Hence, this is the required solution.

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
