Answer and explanation:
To determine number if DVDs that can be bought for $20, we simply check price per DVD then calculate how many $20 can buy
Number of DVDs that can be rented for no more than $20
=$20 divided by cost of each DVD $3.50
=20/3.50
=5.714
=5 DVDs
We round down because 0.714 DVD does not qualify as one DVD
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
The answer in decimal format is 15.7
Or 7 radical 5
