Hello!
The sum of 5/6 and 1/2 is 1 1/2
5/6 > 3/4 so round it to 1.
1/4 ≤ 1/2 ≤ 3/4 so round it to 1/2.
Estimating:
1 + 1/2 = 1 1/2
The difference of 5/6 and 1/2 is 1/2
5/6 > 3/4 so round it to 1.
1/4 ≤ 1/2 ≤ 3/4 so round it to 1/2.
Estimating:
1 - 1/2 = 1/2
Hope this helps!

Answer:y=7x
Explanation:The 1/7 is the slope
We find that the function that could be a stretch of the <em>exponential</em> decay is
. (Correct choice: C)
<h3>What function represents a stretch of a exponential decay function?</h3>
<em>Exponential</em> functions are <em>trascedent</em> functions whose form is described below:
(1)
Where:
- a - Stretch factor
- r - Growth rate
There are two conditions for a <em>stretch</em> factor and <em>exponential</em> decay: (i) a > 1, (ii) 0 < r < 1. Thus, we find that the function that could be a stretch of the <em>exponential</em> decay is
. (Correct choice: C)
<h3>Remark</h3>
The picture is missing and it cannot be found, but statement is still solvable as there is only one choice that responds the question.

1. Find the difference between the sale price and the original price:
90.00 - 67.5 = 22.5
= $22.50
2. Find this difference as a percentage of the original price:
22.5 / 90 = 0.25
0.25 x 100 = 25%
The percentage discount was 25%.
