The rule below shows how Mr. Miller'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. Miller spent on long-distance calls by $0.50, the long-distance rate. Then add $20, the flat monthly charge. A. F(t) = $0.50 + t 20 B. F(t) = $(0.50 t + 20) C. F(t) = $0.50 (t + 20) D. F(t) = $t (0.50 + 20)

    Each minute Miller spends on the phone costs him 0.50 cents. He will always spend $20 a month no matter how long or short his calls. Therefore: f(t) = 0.50t + 20
