I need help with this 2 step equation word problem. I don't need to answer it, I just need to get the equation.

pshichka [43]

So it would be 4x (x meaning the price of each pizza) + 3 for the delivery charge. The equation is 4x + 3. That would be the price of all pizzas plus delivery charge :)

The number of people playing a new phone app game triples every month. When the app first launched, 800 people started playing t

NeTakaya

Answer:

$a_t=ar^{t-1}$

t=6 months

Step-by-step explanation:

We are given that the number of people playing a new phone app game triples every month

When the app first launch , the number of people started playing the game right away=800

According to question

The number of peoples are currently playing the game=194,400

We solve by using the formula of geometric series because we get a geometric series pattern

The number of people playing the game when app game launch=800

The number of people playing game after one month=2400

800,2400,7200,........,194,400

$a_1=800,a_2=2400,a_3=7200,a_t=194,400$

We are finding common ratio

$\frac{a_2}{a_1}=\frac{2400}{800}=3$

$\frac{a_3}{a_2}=\frac{7200}{2400}=3$

Hence, the common ratio is 3 therefor nth term of G.P

$a_t=ar^{t-1}$

a=800,r=3, $a_t=194,400$

Substitute the values then we get

$194,400=800(3)^{t-1}$

$\frac[194400}{800}=(3)^{t-1}$

$243=3^{t-1}$

$3^5=3^{t-1}$

When base are same on both side then the power are equals

Therefore, t-1=5

t=5+1=6

Hence, when there are 194,400 people currently playing the game then

the number of months ,t=6 that have passed since the app launched.
