the function b(n) = 6n represents the number of lights bulbs b(n) that are needed for n chandeliers. If b(n) = 90, what is the value of n?
a.) 15
b.) 12
c.) 96
d.) 540
please hurry!🙃
a.) 15
why 15
b(n) = 6 n = 90
6 n = 90
n = 90 / 6 = 15
To find the value of n when b(n) = 90, we can substitute b(n) = 90 into the given function b(n) = 6n and solve for n.
Starting with:
b(n) = 6n
Substituting b(n) = 90:
90 = 6n
Dividing both sides of the equation by 6:
90/6 = n
15 = n
Therefore, the value of n is 15.
So, the correct option is a.) 15.
