Atrain broke down and the passengers had to alight and take buses to continue their journey. when the first bus came, 1/4 of the passengers tried to board, but 4 of them were not able to get on. when the second bus came, 1/2 o the remaining passengers tried to board, but 6 of them were not able to get on. when the third bus came, 3/4 of the remaining passengers boarded. there were still 8 passengers left stranded. how many passengers were on the train?

Hello,

Please, see the attached files.

Thanks.

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
