Step-by-step explanation:
We can simplify Nancy's cost expression to ...
c +0.09c = c(1 +0.09) = 1.09c
The the total cost of the item of interest is ...

Answer:A on edge
Step-by-step explanation:
Answer:
1. k + 2 (or other way around, it doesn't matter)
2. PY or P×Y
3. 10 - z
Step-by-step explanation:
1. You are adding here, so you add the two terms together.
2. If we had the amount of rulers and how much they cost, we could multiply to find these. Since we don't, we just leave the two variables to be multiplied.
3. It is asking the difference between two numbers, meaning that you need to subtract. With these types of problems, you always use the first number that appears in the problem to start the expression. For instance, if it had listed z first, then you would have done z - 10.
22 - 1 = -3d
21= -3d
21/-3= d
-7 = d
Bring the 1 to the other side by doing the opposite sign, so subtract 1. Solve the left side.
Bring the 3 to the other side by doing the opposite sign, so divide 21 by -3.
End with D equaling -7
