Granny Smith, who was leaving Montreal, boarded a train at four minutes past the hour. After boarding, she stuck her head out of the window and shouted to the ticket man, "How far are we from Toronto?" "All trains take five hours either way," he replied. "How many trains shall I meet on the way?" asked Granny. "A train leaves Toronto at five minutes past the hour, every hour," Answered the ticket men. How many trains will Granny Smith meet?

answer:      

step-by-step explanation:

3

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!
