Adult and student tickets to the high school basketball game are sold each week. For every two adult tickets, seven students tickets are sold. How many total tickets were sold if 92 adult tickets were sold?

x + 4/7

step-by-step explanation:

use cymath

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
