. Many consider it to be the most important unsolved problem in pure mathematics (Bombieri 2000). It is of great interest in number theory because it implies results about the distribution of prime numbers. It was proposed by Bernhard Riemann (1859), after whom it is named.
A rose costs $2.5 and a carnation costs $3.
Step-by-step explanation:
Let,
Roses = x
Carnations = y
According to given statement;
8x+10y=50 Eqn 1
6x+12y=51 Eqn 2
Multiplying Eqn 1 by 6;

Multiplying Eqn 2 by 8;

Subtracting Eqn 3 from Eqn 4;

Dividing both sides by 36;

Putting y=3 in Eqn 3;

Dividing both sides by 48;

A rose costs $2.5 and a carnation costs $3.

Answer:
the profit will be $172
Step-by-step explanation:
The function given is:
p(x) = 2(x-9)^2 + 100
Where x is the price of the each shirt.
if each shirt is sold for $15, hen x = 15.
the profit will be:
p(15) = 2(15-9)^2 + 100
p(15) = 2(6)^2 + 100
p(15) = 2(36) + 100
p(15) = 72 + 100
p(15) = 172
So, the profit will be $172
