After 7 years the population will be 15268.
Given a town has a population of 12000 and grows at 3.5% every year. we have to find the population after 7 years.
As the general growth formula is
where A = Amount after growth
P = Original amount
r = yearly growth rate
t = no. of years
here, P=12000, r=0.035, t=7
Hence, after 7 years the population will be 15268.
To solve this problem, lets use the exponential growth formula which is:
A = total amount
P = original amount
r = growth rate (decimal)
t = years
Before we plug in the values, don't forget to change 3.5% to its decimal form.
3.5% -> -> 0.035
Lets plug in the values:
The population after 7 years will be 15,267.
i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.
i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).
in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.
then the standard form of the equation is finding an expression of y in function of x
hope that .
do you confirm there was a mistake in the question?
question: how many people can she serve?
answer: she can serve 16.66666667 people. so she can only give 16 people a complete serving.
question: does she have enough ice cream for her guests?
answer: no. explanation: she only has enough for 16 people to have a full serving. however, she can give a 17th person a partial serving.
