So for this we will be using a system of equations, with one equation representing Shakira's sales and the other representing Jeff's sales. Our equations are such (Let x = oranges and y = grapefruit)

For this, I will be using the elimination method. So firstly, multiply both sides of the second equation by -4: 
Next, add 5x+8y=235 and -12x-8y=-340 to get -7x = -105 . From here we can solve for x.
For this, just divide both sides by -7, and your answer is going to be x = 15.
Now that we know what x is, just substitute x for 15 in either equation to solve for y. For this I will be using the second equation.

Since we know that oranges cost $15 and grapefruit cost $20, just add them together to get your answer, which is $35.
Answer:
The address of Ainsley is 24 and that of Lane is 25.
Step-by-step explanation:
All the houses on sequence lane have an address whose numerical portions are greater than that of the prior house.
Now, if Ainsley and Lane are next-door neighbors and the sum of the numerical portions of their addresses is 49.
Let the Ainsley has the address with numeric portion x, then Lane has the address with numeric portion x + 1.
Therefore, x + (x + 1) = 49
⇒ 2x = 48
⇒ x = 24
So, the address of Ainsley is 24 and that of Lane is 25. (Answer)
