Larry is 11 years old. One day, his granddad took him and his younger brother to a basketball game. The tickets for the game were priced at $17 for adults (a) and $13 for children (13 years and younger) (c). What is the expression for the total cost of the tickets for Larry's family and what was the total cost?

Your answer would be 48 and heres how I know :3!

Larry is under the age of 13 so he cost 13$ and so does his little brother! His grandfather costs 17$ because he is an adult.

SO overall= 13 + 13= 26 + 17= 48 !

Sorry if late!

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
