Since 158 minus 113 is 45, Manny only has to read 45 pages. If Manny reads nine pages a day, you have to divide 45 by 9, which leaves you with 5. It will take Manny 5 days to finish the book.
I assume that you mean 18s-27t
Let's go through each answer, and see which one is right.
A) 9 × 2(s-t)
Simplify that.
18(s-t)
18s-18t
So, A) is incorrect.
B) 9(2s-3t)
Simplify.
18s-27t
B) is the correct answer
C) 6(3s-4t)
Simplify.
18s-24t is incorrect because it is not equal to 18s-27
So, C) is incorrect.
D) 6 × 3(s-t)
Simplify.
18(s-t)
18s-18t
D) is incorrect.
So, your answer is B) 9(2s-3t)

The jeweler bought it for (1235.55 * 73.5) = 90812.925...expenses
and the jeweler sold it for (1376.44 * 73.5) = 101168.34...revenue
profit = revenue - expenses
profit = 101168.34 - 90812.925 = 10355.415 rounds to 10,355.42 <==
