Starting at 7:00 a. m., Lin spent a day hiking through a canyon. This graph shows her elevation (in meters) at some different times. Negative values of represent times earlier than noon, and positive values of represent times later than noon. e. Lin climbed downward from 2:00 p. m. to 3:00 p. m.
Add a point to the graph that shows her possible elevation at 3:00 p. m.

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!

hi! i think the answer is 1/2 : )
