Let's use the variable E to represent the total value spent by Elena and T to represent the total value spent by Taniy.
If Elena spent $7.45 plus the cost of 3 pounds of cherries, the expression for the amount she spent is:

Taniy spent $3.35 plus the cost of 2 pounds of cherries, so the expression for the amount the spent is:

To find how much more Elena spent, let's subtract both expressions:

Therefore the answer is 4.1 + p.
Answer:

Step-by-step explanation:
The average rate of change can be found by using the following formula

Since the interval goes from -7 to 2, we should find the y-values that correspond to x=-7 and x=2.
By inspection of the graph, we can clearly see that when x is -7, y is -7 as well and when x is 2, y is 5.
Now that we know this, we can simply plug these values into the formula!

Good luck!
