The formula 1= prt gives the simple interest / earned on a n account where an amount p is deposited at an interest rate r for a certain numbers of years t. use the table to order the accounts from least to greatest interest earned after 5 years.

account. p. r.
a. 350. 4

b. 500. 3.5

c. 280. 4.25

is only a line? i think so

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
