The costs of 5 similar digital cameras and 3 similar video cameras is $3,213. Each video camera costs 4 times as much as each di
mariarad [96]
Let,
digital cameras be "x"
video cameras be "y"
Now,
According to the question,
5x + 3y = $3,213..................................................equation (1)
y = 4x..................................................................equation (2)

Taking equation (1)
5x + 3y = $3,213
Substituting the value of "y" from equation (2), we get,
5x + 3(4x) = $3,213
5x + 12x = $3,213
17x = $3,213
x = $3,213 / 17
x = $189

Taking equation (2)
y = 4x
Substituting the value of "x", we get,
y = 4 ($189)
y = $756

Now,
John buys a digital and a video camera. So, it costs him ($189 + $756) = $945

The cost (in dollars) in making b bracelets is represented by 4+5b. The cost (in dollars) of making b necklaces is represented b
ddd [48]
Answer:

P(b)=3b+2

Step-by-step explanation:

The cost (in dollars) in making b bracelets is represented is

B(b)=4+5b

The cost (in dollars) of making b necklaces is

N(b)=8b+6

To find how much more it will cost to make b necklaces than b bracelets, we find the difference,

P(b)=N(b)-B(b)

P(b)=8b+6-(4+5b)

P(b)=8b+6-4-5b

P(b)=3b+2

This is a polynomial in descending powers of b, hence it is in standard form;
