the rule below shows how mr. perez's long-distance phone company computes his monthly bill. which answer expresses that rule in the form of an equation?


multiply the number of minutes mr. perez spent on long-distance calls by $0.45, the long-distance rate. then add $33, the flat monthly charge.

Af(t) = $(0.45 t 33)

Bf(t) = $t (0.45 33)

Cf(t) = $0.45 t 33

Df(t) = $0.45 (t 33)
