Answer:
B is your answer.
Step-by-step explanation:
Depends on 18/36 = 72/444, because 444 doesn't make sense at all. None of the others are equivalent. If it's 72/144 then this is the answer

Well, let's look at the answer choices.
A) If you want to fond the total cost of two sweaters you would add, not divide. So this isn't it.
B) To find out how much older someone is you would subtract. So this isn't it either.
C) To find out how many desks are needed you would multiply, since you know you need 3 rows of desks with 7 students each (3 x 7). Again, not it.
D) To find out how many pencils each student would get, you'd divide. You would divide 56 by 9. So your answer is D.
The expression that can be used to show the relationship between the number of days and the total dollars (t) he spends is t = 30d
<h3>How to write expressions</h3>
- Cost of renting a car per day = $30
- Number of days Paul rents the car = d
- Total amount John spends = $t
The equation:
Total = cost per day × number of days
t = 30 × d
t = 30d
