Community Gym charges a $40 membership fee and a $65 monthly fee. Workout Gym charges a $170 membership fee and a $55 monthly fe

sergejj [24]

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.

Justin bought some yarn from his favorite craft store. He can make one scarf with 3/5 of a ball of yarn. If he purchases 15 ball

Elena L [17]

He can make 25 scarves from 15 balls of yarn.

Step-by-step explanation:

Given,

Yarn used for one scarf = $\frac{3}{5}$ of a ball

Yarn purchased = 15 balls

Let,

x be the number of scarves.

Yarn used for one scarf*number of scarves = Yarn purchased

$\frac{3}{5}x=15$

Multiplying both sides by $\frac{5}{3}$

$\frac{5}{3}*\frac{3}{5}x=15*\frac{5}{3}\\x=\frac{75}{3}\\x=25$

He can make 25 scarves from 15 balls of yarn.

$\sum\limits_{k=1}^{\infty}420\left(\dfrac{1}{6}\right)^{k-1}$

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 :

$S=\dfrac{a_1}{1-r}$

We have:

$a_1=420\left(\dfrac{1}{6}\right)^{1-1}=420\left(\dfrac{1}{6}\right)^0=420\\\\r=\dfrac{1}{6}$

substitute:

$S=\dfrac{420}{1-\frac{1}{6}}=\dfrac{420}{\frac{5}{6}}=420\cdot\dfrac{6}{5}=84\cdot6=504$

Answer: d. Converges, 504.
