Question 4.
Multi-Step Dan has 140 markers. How many more boxes of 10 markers does he need to get so that he will have 180 markers in all?
___________ boxes of markers
Answer: 4 boxes of markers.
Explanation:
The number of markers Dan has=140
The number of markers in each box=10
The number of markers is needed so that he will get 180 markers=X
The number of boxes needed to get=Y
first, calculate the X value.
X=180-140
X=40
Therefore, 40 markers are needed more to get 180 markers.
Now to calculate the Y value we need to divide X value and markers in each box.
Y=40/10
Y=4
Therefore, 4 boxes of markers are needed so that he will get 180 markers.

(A) 25
(B) 10
(C) 250
Answer: Option A is correct.
Texas Go Math Grade 2 Lesson 1.3 Answer Key Explore 3-Digit Numbers h7
Explanation:
The number of red ribbons Amy orders=250
The number of red ribbons needs to fill in each bag=10
The number of bags needed to fill 250 ribbons=X
Now divide to get the answer
X=250/10  (0 and 0 gets cancel, 25/1 is nothing but 25)
X=25
Therefore, 25 bags are needed to fill 250 red ribbons. In each bag, there will be 10 red ribbons.

Question 8.
Multi-Step Saul has 130 baseball cards. How many bags of 10 baseball cards does he need to get so that he will have 200 baseball cards in all?
(A) 7
(B) 70
(C) 60
Answer: Option A is correct.
Texas Go Math Grade 2 Lesson 1.3 Answer Key Explore 3-Digit Numbers h8.1
Explanation:
The total number of baseball cards does saul has=130
The number of cards in each bag=10
The number of bags=Y
The number of baseball cards needed to get 200 baseball cards overall=X
Already he has 130 baseball cards so we need to find out the extra cards to get 200 baseball cards. If we subtract cards he has now and overall cards he wants.
X=200-130
X=70.
Therefore, add 70 to the 130 to get the 200 baseball cards.
Thus, 70 cards are needed to get 200 cards overall.
To calculate the number of bags divide X value and cards in each bag.
Y=70/10
Y=7.
Therefore, 7 bags are needed.
