Xander goes to the movies with his family. each family member buys a ticket and two boxes of popcorn. if there are five members of his family, let t represent the cost of a ticket and p represent the cost of a box of popcorn. write two different expressions that represent the total amount his family spent. explain how each expression describes the situation in a different way.

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

what? ?
