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

First, let's find out the amount it costs to rent one movie.
175-172.25=2.75
172.25-169.50=2.75
169.50-166.75=2.75
$2.75/movie rental
-----------------------------------------------------------
A=175-2.75n
where a is the amount on the card
175 is the original amount in the card
2.75 is the cost of a movie rental times n amount of rentals
-------------------------------------------------------------------------------
n=175/2.75
=63.63
=63
n is the amount of weeks she can rent a movie
She can rent movies for 63 weeks in a row
