1.65

You can substitute in the values of p, n and e to get the equation:
5700 = 4000c - 900

add 900 to both sides and you get

6600 = 4000c

divide both sides by 4000 and you get

1.65 = c

so the answer is 1.65

Answer:

You can decide where to put the first digit because you know 153 doesn't fit into 6 or 61. But you know it can fit into 613. You put it there.

Quincy sold three times as many magazines as Olivia. Trenton sold two less than twice the number of magazines that Quincy sold.

Anastaziya [24]

Olivia sold 14 magazines.

Step-by-step explanation:

Total magazines sold = 138

Let,

Magazines sold by Olivia = x

Magazines sold by Quincy = y

Magazines sold by Trenton = z

According to given statements;

x+y+z=138 Eqn 1

Quincy sold three times as many magazines as Olivia.

y = 3x Eqn 2

Trenton sold two less than twice the number of magazines that Quincy sold.

z = 2y-2 Eqn 3

Putting value of y from Eqn 2;

$z=2(3x)-2\\z=6x-2\ \ \ \ Eqn\ 4$

Putting value of y from Eqn 2 and value of z from Eqn 3 in Eqn 1

$x+3x+(6x-2)=138\\4x+6x-2=138\\10x=138+2\\10x=140\\$

Dividing both sides by 10

$\frac{10x}{10}=\frac{140}{10}\\x=14$

Olivia sold 14 magazines.
