In 2014, the cost to mail a letter was 49 cents for up to one ounce. every additional ounce cost 21 cents. which recursive function could be used to determine the cost of a 3-ounce letter, in cents?
a. aβ = 49; aβ = aβββ + 21
b. aβ = 0; aβ = 49aβββ+21
c. aβ = 0; aβ = aβββ + 49
d. aβ = 0; aβ = 21aβββ + 49
(in the answer selection above, i used x's instead of n's because i couldn't find the subscript for n. i don't know if that makes a difference or not.)
