Bryan gave a cashier $15 to pay for a sandwich and chips. He received $3.65 in change. If the sandwich cost $9.99, how much did the chips cost?

1.36 for the chips

Step-by-step explanation:

15-9.99=5.01

5.01-3.65=1.36

$1.36

Step-by-step explanation:

First you do $15.00 - $3.65 = $11.35 Then, $11.35 - $9.99 = $1.36.

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

b mark me branliest thx
