Answer:
The regular price was $30.
Step-by-step explanation:
The bookstore sells used books at 40% discount off the price of new books. This means, after the discount, the price of a used book will be 100% - 40% = 60% of the original price.
Now, if the price of the used book is $18, we know that is is 60% of the price of the book when it was new.
Let us call , the price of the book when it was new, then we know that
<em>(this says that 60% of the original price is $18.</em><em>)</em>
We solve for and get
The price of the book was $30 when it was new.
Solve the problem then state if it's true or false- this is an order of operation problem. 3+2/3(3-X) this is the problem. Now distribute, 3+ 2/3(3)- 2/3(x)= 3+2- 2/3x so the final expression would be 5-2/3x I don't know about the <-7 part but that's the solution to the first one
A <u>reasonable tip </u>would be $5.00
Rosita paid $27.08 an wants to tip a whole dollar <u>closest to 20%. </u>
The first step is therefore to find out 20% of $27.08.
= 20% x 27.08
= $5.42
The closest whole dollar depends on the first decimal point.
If it is 5 and above, the tip would be $5 as we would round down.
If it is 4 and below, the tip would be $6 as we would round up.
The<u> first decimal </u>is 4 so we would round down to $5.00
The tip would therefore be $5.00
