Answer:
Peggy is correct, their total bakes sale = $396.75
Step-by-step explanation:
Using estimation to help Peggy explain why Leslie reasoning is incorrect.
From the question we can see that:
First bake sale they made = $79.35
4 more bake sales making the same amount = 4 × $79.35
The total amount they would make from the bake sales =
$79.35 + (4 × $79.35)
= $396.75
Peggy was right. Leslie's reasoning was incorrect.
- An isosceles triangle ABC
- AD is a bisector of ∠A

Question Explanation:
In other words you can write 200,00 using a whole number and a power 10 using scientific notation!
In scientific notation you want a number less than 10 multiplied by 10 to the power of a number.
-----------------------------------
Solution:
200,000 / 10 = 20,000
20,000 / 10 = 2,000
2,000 / 10 = 200
200 / 10 = 20
20 / 10 = 2
I divided 200,000 by 10 five times to get a number less than 10.
So, 5 is going to be the exponent.
