Answer:
I don’t get most of it, but I believe “doubles” means two of the same number added together. For example, 9+9 is a double. I think “doubles +1” means a double and add one. For example, 6+6+1. If I were your sister, I would write “9+9 = 18” for doubles and “6+6+1 = 13” for doubles +1.
I hope I helped!
Estimation would give you an answer close to the actual answer so you can see if your answer is reasonable depending on how close the estimate is
Answer:
$16 per pound
Step-by-step explanation:
We want to find the price per pound.
Therefore, we must divide the cost by the pounds.

We know it costs $144 for 9 pounds of pears. Therefore, $144 is the cost and there are 9 pounds.

Divide.

It costs $16 for each pound of pears.
Combine costs
59.99(3) + 75 = 179.97 + 75
179.97 + 75 = $254.99 (total cost)
Now add tax: 8% = 0.08
254.99 * 0.08 = 20.3992
254.99 + 20.3992 = 275.3892
Solution: bill would be around $275
