Answer:
And the interpretation for this value is that the oak tree is have a height of 40% lower than the Redwood tree
Step-by-step explanation:
For this case we can calculate the % of change with the formula of relative change given by:
For this case the Base value is 200 ft since represent the heigth of the redwood tree selected as the base
And the New value would be 120 who represent the height of the oak tree
If we replace into the formula we got:
And the interpretation for this value is that the oak tree is have a height of 40% lower than the Redwood tree
2 numbers are 0.45 and 0.4. 0.4 would equal 2/5 in simplest form. 0.45 in simplest form is 9/20. hope this helps.
Answer:
(c) $80
Step-by-step explanation:
Each discounted price corresponds to the original price multiplied by a factor related to the discount. For a discount fraction of 'd', the multiplier is (1 -d).
This means you can use any of the lines in the table to find the original price.
<u>5% disount</u>: (1 -5%)·p = $76 . . . . where p is the original price
p = $76/0.95 = $80 . . . . . . . the original price
<u>10% discount</u>: (1 -10%)·p = $72
p = $72/0.90 = $80
<u>25% discount</u>: (1 -25%)·p = $60
p = $60/0.75 = $80

<em>Additional comment</em>
The table values for 5% and 10% differ by 5% and $4. That means 5% of the original price is $4. There are two things you can do with this:
- add back that 5% to the 5%-discounted price: $76 +4 = $80
- multiply that 5% by 20 to get 100% of the original price: 20(5%) = 20($4) ⇒ 100% = $80.
