Y = 30/20x + 20
( i haven’t done this in a while but i’m pretty sure this is right)
Marco rounded the hundredths place since after the decimal it is the tenths then the hundredths then the thousands place
Answer:
60.32
Step-by-step explanation:
Answer:
Step-by-step explanation:
Exponential growth function can be represented as follows
y =
Here y increases exponentially with respect to t . As t increases , rate at which y increases is increases .or
dy / dt =by , or rate of increase depends upon y itself
dy / y = bdt
integrating on both sides
lny = bt
y = 
It represents very fast increase in y .
The unrestricted growth of population of human being is an example of exponential growth . As population increases , rate of growth of population also increases.
For exponential decay function
y = 
The decay of a radioactive material is an example of exponential decay function.
So the total number of movie tickets sold was 1200. This means that a + c = 1200 because a represents the number of adult tickets purchased and c represents the number of child tickets purchased. The total money they made off the movie was $6400. This means 7 multiplied by the number of adult tickets would result in the total they earned off adult tickets, and 3 multiplied by the number of child tickets would result in the total they earned off child tickets. This total equals 6400. So 7a + 3c = 6400. These are our two equations: a + c = 1200 and 7a + 3c = 6400. The answer choice that matches this is choice A, so your answer is A. Hope this helps.
