Answer:

Rachel bought 6 pounds of coffee.

Step-by-step explanation:

First, do $70-$25.36, because that will give you the total amount of money she spent on coffee.

$70-$25.36= $44.64.

Rachel spent<u> $44.64 </u>on coffee.

Next, you know that every pound of coffee costs $7.44.

So, $7.44x = $44.64

x= the number of pounds of coffee Rachel purchased.

So, we have to now isolate x.

$7.44x / $7.44 = $44.64 / $7.44

<u>x= 6</u>

Therefore, Rachel purchased 6 pounds of coffee.
