Question

For an overeas, splint charges $7 for the first minute and then $3 for each additional minute. How much would a 15 minute call cost?

Answer 1

7 + 3m = $
m represents the number of minutes after the first one. in this case, m = 14 because we don’t count the first minute since it has its own price.
7 + (3*14)
7 + 42 = 49
it would cost $49 dollars for a 15 minute overseas call
