A pencil costs .27 and a pen costs .32. You buy six pencils and the total cost is 4.18 How many pens did you buy?

skelet666 [1.2K]

Answer:

8 pens

Step-by-step explanation:

<h2><u>Finding the number of pens bought </u></h2>

pencil costs 0.27

pen costs 0.32

6 * pencils + x pens = 4.18

6 * 0.27 + x * 0.32 = 4.18

1.62 + 0.32x = 4.18

0.32x = 4.18 - 1.62

0.32x = 2.56

x = 2.56/0.32

x = 8

<u>hence 8 pens were bought </u>

A toy store owner estimates that by charging x dollars each for a certain toy, he can sell 40−x toys each week. The quadratic eq

djyliett [7]

Answer:x=20

Step-by-step explanation:

Given

selling Price of Toy is x dollars

he can sell 40-x toys each week

Thus Revenue Generated from selling 40-x toys at x dollar can be given by

$R=-x^2+40x$

To get maximum Revenue differentiate R with respect to x and equate it to 0

therefore $\frac{\mathrm{d} R}{\mathrm{d} x}=-2x+40$

$-2x+40=0$

$x=20$

thus for maximum Revenue owner sells 20 toys each week

Max Revenue $R=-(20)^2+40\times 20=-400+800=$ 400$
