Brian invests £2300 into his bank account. He receives 10% per year simple interest. How much will Brian have after 2 years?

im pretty sure  $460 idk

Step-by-step explanation:

Find an interest by using the formula  

I=P⋅i⋅t

, where I is interest, P is total principal, i is rate of interest per year, and t is total time in years. In this  

P = $2300, i = 10% and t = 2 years,

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 can you with this answer
