At the end of the school year all 8th grade students and teachers go to Six Flags. There is a combined total of 400 people attending. Each student’s ticket cost $40 and each teacher’s ticket cost $45 to enter the park. The total amount spent for all people to go was $16,100. How many teachers were on the trip? Let x represent the number of student tickets, and y represent the number of teacher tickets

(2,9)

i think thats the answer i checked it on google

step-by-step explanation:

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)

you have to put the graph on here with the question
