Answer: 13 months
Step-by-step explanation:
I made these into equations first.
40 (initial fee) + 65x (x is the number of months) = total cost
170 (initial fee) + 55x (x is the number of months) = total cost
There are two ways to go about this.
1. Put it into a graphing calculator (or a site like desmos) and see where the lines intersect (the easiest way)
2. If you don't have access to either of those, do the old guess and check by plugging in numbers of months until you get your desired answer.
He can make 25 scarves from 15 balls of yarn.
Step-by-step explanation:
Given,
Yarn used for one scarf =
of a ball
Yarn purchased = 15 balls
Let,
x be the number of scarves.
Yarn used for one scarf*number of scarves = Yarn purchased

Multiplying both sides by 

He can make 25 scarves from 15 balls of yarn.

The infinite geometric series is converges if |r| < 1.
We have r=1/6 < 1, therefore our infinite geometric series is converges.
The sum S of an infinite geometric series with |r| < 1 is given by the formula :

We have:

substitute:
