Answer:
hiiiii
your answer is here !
Step-by-step explanation:
Given cost price of the book = $100
Profit% = 10%
We know, selling price = (100 + profit%)cost price/100
= (100 + 10)100/100
= (110)100/100
= 110 × 100/100
= $110
Therefore, the selling price of the book is $110.
follow me !
Answer:
$110
let cost of book be X
y = selling price
X+ ( 10x/100)= y
(100x + 10x)/100 = y
putting the value of x
100 + 1000/100 = y
100 + 10 = y
$110 = y
therefore the selling price of the book was $110
