Answer:
1. $0.24
2. 89.2 miles
Step-by-step explanation:
To get the unit price, divide the total price by the amount that was purchased.
1. 3.12/13 = $0.24
For the second one, get the distance traveled per hour first then multiply by 8.
22.3 / 2 = 11.15
11.15 x 8 = 89.2
Since y=2x+1 does not pass through the origin (i.e. there exists the constant term of 1 ), the variables y and x are not directly proportional - though, they do have a linear relationship.
You would need to isolate the "X" variable because it is common in all 3 equations.
14-21= -7
-7 is your answer ^^

First, we need to find how much a single pound of apples costs.
Do this by dividing.

Now, write an equation.

This represents that the cost equals 3.5 times the number of apples.
