Question

Suppose a local vendor charges $2 per hot dog and that the number of hot dogs sold per hour is given by
x(t) = −4t2 + 20t + 64,
where t is the number of hours since 10 AM,
0 ≤ t ≤ 4. Find an expression for the revenue per hour R as a function of x?

Answer 1

\[R = 2x(t) = -8t^2+40t+128\]

Answer 2

how would i do (r dot x)(t)? do i put x in r or times the polynomials?

Answer 3

you mean\[(R\ o\ x)(t)\]?

Answer 4

yea
