The fifth-grade classes at brookfield school used five identical buses to go on a field trip. •there were a total of 40 seats on each bus. •all of the seats on four buses were filled. •the fifth bus had 4/5 of the seats filled. •1/8 of all the passengers on the buses were adults. how many adults went on the field trip.

First things first, you need to figure out the amount of passengers on the fifth bus.

Solution:
40 x 4
--      -  = 32 passengers
 1  x 5
*The fifth bus has 32 people.
You can now figure out the total number of passengers in all of the buses.

(40 x 4) + 32 = 192
*Overall, all 5 buses have a total of 192 passengers.
Since you have the total number of passengers, you can now figure out the numbers of adults who went on the field trip, which is 1/8 of all the passengers.

Solution:
192 x 1
   - = 24 passengers
  1   x 8

The final answer is: 24 adults went on the field trip.

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

1 the 1st term, 3 the 2nd term, 6 the 3rd term,etc.

note the following:

from the 1st term (1) to the 2nd term (3), we go up by 2,from the 2nd term (3) to the 3rd term (6), we go up by 3from the 3rd term (6) to the 4th term (10), we go up by 4, andfrom the 4th term (10) to the 5th term (15), we go up by 5.

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

The discount is 8.70 . you dont tell us the percent of tax added so there is no way to find out, unless i'm not seeing anything. without tax its 37.70
