The rule below shows how Mrs. Rousseau's long-distance phone company computes her monthly bill. Which answer expresses that rule in the form of an equation? Multiply the number of minutes Mrs. Rousseau spent on long-distance calls by $0.42, the long-distance rate. Then add $24, the flat monthly charge.

so then n=number of long distance calls, then add the flat rate

long distance cost=number of calls times cost per clll or n times 0.42 or 0.42n
the flat rate is 24

so total is c so
c=24+0.42n
