<span>Starting with the equation f = v + at
Subtract v on both sides:
f - v = at
Divide both sides by a:
(f - v) / a = t
Swap the sides:
t = (f - v) / a

Answer:
The artist begins to profit when n > 8.18
That means the quantity of necklaces must exceed 8.18.
Step-by-step explanation:
Given
let n represent the number of necklaces
booth fee= $135
The expense for materials per necklace = $4.5n
the overall selling price for all necklaces = $12n
total costs= booth fee + material costs = $135 + 4.5n
profit = selling price - total costs
12n > 135 + 4.50n
By solving for n, we find
12n=135 + 4.50n
12n + 4.5n = 135
16.5n = 135
n = 135/16.5
n = 8.18
Hence, the artist achieves profits when n > 8.18.
No. 16.454 contains an extra digit at the end. If that final 4 were a 0, the two numbers would be equal.
The expression for total profit qualifies as a polynomial, contains a constant term, and can also be classified as a binomial.
The pairs that have an HCF of 3 and an LCM of 45 are (3,45) and (15,9).
