Question

A forest owned by the Jumbo Lumber Corporation contains 6,359 trees. If Jumbo Lumber cuts down 60 trees every day, which function can be used to find the number of trees, n, left in the forest after t days?

a. n(t)=6,359-60t
b. n(t)=(6,359-60)t
c. n(t)=6,359t-60
d. n(t)=6,359+60t

Answer 1

Do you need the answer only or you would like to think it over with help?

Answer 2

Preferably think it over with help! I'd like to know how to solve probs like this later on if you don't mind:)

Answer 3

not at all, first you have to collect what you know. 6359 trees in the forest. they cut 60trees / day.
So the original number of trees will be less and less.

Answer 4

Ok. So I can rule out the addition option.

Answer 5

yes :) definitely not good. how much trees they cut in one day? and in 2? and in 3?... this is the next you have to think it over

Answer 6

Hmm... 60 will have the variable?

Answer 7

yes, the original number of trees is a constant, does not depend on anything.

Answer 8

Ok. So I know that I must subtract and that 60 has the variable. That leaves me with A and B!

Answer 9

if you check B actually it is 6359t-60t and we already know that the original number of trees is always shows the original number of trees, will not change.

Answer 10

Oooh! I see! Because the variable is outside the parenthesis; distributive property.

Answer 11

yes (a+b)*c -> a*c + b*c

Answer 12

Thanks so much for your help!!! I really appreciate it! : D xxxx

Answer 13

another way to approach, to try to write the equation and compare with the solutions.
not at all.

Answer 14

Awesome! I'll keep that way in mind, as well. Thanks again! xx
