X= 1 pound of coffee
3x=$18.96
divide both sides by 3
x= $6.32
for every pound of coffee you buy, it costs $6.32
here is a graph where it is mirror flipped due to my camera
it is linear and grows at a constant rate

Answer:

We know that 3 pounds of coffee cost $18.96. We can use the rule of three to find the cost per pound

x=1lb\frac{\$18.96}{3lb}=\$ 6.32

This means that one pound of coffee costs $6.32.

Having this ratio of change, we can express a linear function that models this problem

y=6.32x

The image attached shows the relationship between these two variables, which has a linear behaviour.

Where y represents cost in dollars, and x represents pounds.

An infinite number of ratios are equivalent to 3:8. How
Inessa05 [86]

Answer:

See below, please!

Step-by-step explanation:

There are infinite number of ratios equivalent to 3:8 because both numbers can be multiplied by a common number or divided by a common number.

For example, 9:24 would still be equivalent to 3:8 because the common number in our case is 3. See what I mean?

Hope this helped!
