Rachel received a $70 gift card for a coffee store. she used it in buying some coffee that cost $7.44 per pound. after buying the coffee, she had $25.36 left on her card. how many pounds of coffee did she buy?

6 pounds.

Step-by-step explanation:

70-25.36= 44.64 (the amount of money she spent)

44.64/7.44 (per pound cost)= 6

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 $44.64 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

x= 6

Therefore, Rachel purchased 6 pounds of coffee.

step-by-step explanation:

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
