This ODE is separable; we have

$\dfrac{\mathrm dy}{\mathrm dt}=ky\implies\dfrac{\mathrm dy}y=k\,\mathrm dt$

Integrating both sides gives a general solution of

$\ln|y|=kt+C\implies y=e^{kt+C}=Ce^{kt}$

B is the only choice that is applicable.

Hi!

The options regarding the inequalities are not listed, though we can still proceed to write the inequality.

From the problem statement you cannot spend more than $50

and you are charged admission fee of $6 flat

a ride cost $2.50 per ride

the number of rides is given as r

yet in all you must not go beyond your limit

Therefore the inequalities can be presented as

$6+2.5r\leq 50$
