Motor riders Vladimir and Varya started their rides from two points that are 160 miles apart. Laika, Vladimir's pet parrot started chasing Vladimir's motorcycle and overtakes him and meets Varya. Then Laika flew back towards Vladimir. The parrot then started flying back and forth between the two riders. The parrot flew at the speed of 25 mph, while Vladimir and Varya's speed was 20 mph. What was the total distance that Laika flew in miles​

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!
