Aclass is going on a field trip to see a movie. each ticket is $10.00. the number of students, n, who will receive a $10.00 ticket is proportional to the total cost, c, of all the tickets. which equation could be used to find the total cost of all the tickets?

if x decreases by 4 then y increases by 10

step-by-step explanation:

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x
