Original cost of the book = $25
Percentage of discount got by Marilyn while buying the book = 15%
Amount of discount got by Marilyn while buying the book = (15/100) * 25
= 375/100
= 3.75 dollars
So
The amount paid by Marilyn for buying the book = (25 - 3.75) dollars
= 21.25 dollars
<span>So the total amount paid by Marilyn for buying the book is $21.25.
I hope the procedure for doing this problem is clear to you.</span>
Answer:
The slope is 35 and it means the technician earns $35 per hour.

Answer:
k≥-1.5
Step-by-step explanation:
-(5k-3) ≤ 15 + 3k
-5k+3 ≤15 +3k
+5k +5k
3≤15+8k
-15 -15
-12 ≤ 8k
divide both sides by 8
-1.5 ≤ k
or k≥-1.5
Hope this Helps!!!
