You buy 3 tickets for $48 total for jazz concert on Friday night. Your friend buys 2 tickets for $36 total for the jazz concert on Saturday night. Your brother collected $96 from his friends to buy 6 tickets. Which night can they go to the concert? Did they buy the less expensive tickets? Explain?

Your brothers and his friends paid less for the tickets compared to you and your friends. They went Friday night.

Step-by-step explanation:

48/3 = How much per ticket you paid / $16

36/2 = 18 / How much your friend paid for each ticket.

Tbh this question is very confusing, so I won't guarantee an exact correct answer for you. I think there should be more details added

-81 -56 -27 0 81

step-by-step explanation:

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
