Answer:

5 in

Step-by-step explanation:

x = number of in cut from each side

V = 750

V=lwh

l = 25 -2x

w = 20-2x

h =x

V = (25-2x)(20-2x)x

(25-2x)(20-2x)x = 750

4x^3-90x^2+500x-750=0

Factor it and solution is 5/2,5,15

You earn $9.50 per hour at your summer job. Write and solve an inequality to find the number of hours you need to work to buy a

masha68 [24]

Let
h
represent hours worked.
Now, we know the pay for one hour of work is
$
9.50
. So, the amount of pay for
h
hours worked is given by
9.50
h
.
Furthermore, since we're saving for a camera that costs
$
247
,
we want at LEAST
$
247
(but it's okay if we have more). So, we'll be using
≥
in the inequality.
So, our inequality is
9.50
h
≥
247

To solve, we simply divide both sides by
9.50
:
h
≥
247
9.50

h
≥
26

You need to work at least
26
hours to buy the digital
