HELP PLEASE!! Tonya's dog-walking service charges a flat rate of $20 per
month, plus $3 per mile that each dog is walked. Beth does
not charge a monthly fee for her dog-walking service, but she
charges $5 per mile that each dog is walked. Select the
equation and solution to find the number of miles m for which
Tonya and Beth would charge the same amount.
8m = 20
20 + 3m = 5m
m=2.5
20 +3m +5m = 0
m = 12
Om = 10

step-by-step explanation:

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

note the following:

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
