Stells [14]
Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
2^n - 3 = 83 
<span>2^n = 86 </span>
<span>ln(2^n) = ln(86) </span>
<span>n*ln(2) = ln(86) </span>
<span>n= ln(86)/[ln(2)] (which is the same as "log base 2 of 86") </span>
<span>n= 6.426264755</span>

John &amp; friends brought 4 bags of popcorn and 3 sodas at the movie for a total of 13.50. At the next movie John &amp; friend
scoray [572]

Answer:

The cost of 5 bags of popcorn and 2 sodas is 14.25 units.

Step-by-step explanation:

We are given the following in the question:

Let x units be the cost of a popcorn bag and y units be cost of soda.

The cost of 4 bags of popcorn and 3 sodas is 13.50.

Thus, we can write the equation:

4x + 3y = 13.50

The cost of 2 bags of popcorn and 5 sodas is 12.00

Thus, we can write the equation:

2x+5y=12

Solving the two equations, we get,

4x + 3y-(4x+10y) = 13.5 - 24\\\Rightarrow -7y  =10.5\\\Rightarrow y = 1.5\\\Rightarrow 2x + 5(1.5) = 12\\\Rightarrow x = 2.25

Thus, the cost of popcorn bag is 2.25 units and the cost of a soda is 1.5 units.

Cost of  5 bags and 2 sodas

==5x+2y\\=5(2.25) + 2(1.5)\\=14.25

Thus, cost of 5 bags of popcorn and 2 sodas is 14.25 units.
