Here are the solutions to the addition word problems. I have worked through each one step by step to ensure the calculations are correct.
1) Olivia baked 38 apple pies and 17 pumpkin pies. How many pies did she bake in all?
*
Step 1: Add the ones place: $8 + 7 = 15$. Write down the 5 and carry over the 1.
*
Step 2: Add the tens place plus the carry-over: $3 + 1 + 1 (\text{carry}) = 5$.
*
Calculation: $38 + 17 = 55$
2) There are 23 books in the first rack of a bookshelf. If there are 49 books in the second rack, how many books are there in all?
*
Step 1: Add the ones place: $3 + 9 = 12$. Write down the 2 and carry over the 1.
*
Step 2: Add the tens place plus the carry-over: $2 + 4 + 1 (\text{carry}) = 7$.
*
Calculation: $23 + 49 = 72$
3) On Halloween night, Kate decorated her yard with 75 carved pumpkins and 92 scary face masks. What is the total number of Halloween decorations that Kate used?
*
Step 1: Add the ones place: $5 + 2 = 7$.
*
Step 2: Add the tens place: $7 + 9 = 16$.
*
Calculation: $75 + 92 = 167$
4) 51 girls and 89 boys volunteer to help at a fundraising event. How many children volunteer at the fundraiser?
*
Step 1: Add the ones place: $1 + 9 = 10$. Write down the 0 and carry over the 1.
*
Step 2: Add the tens place plus the carry-over: $5 + 8 + 1 (\text{carry}) = 14$.
*
Calculation: $51 + 89 = 140$
5) A food truck sold 40 grilled cheese sandwiches and 36 club sandwiches today. How many sandwiches did the food truck sell altogether?
*
Step 1: Add the ones place: $0 + 6 = 6$.
*
Step 2: Add the tens place: $4 + 3 = 7$.
*
Calculation: $40 + 36 = 76$
6) A stationery store has 66 cans of red paint and 84 cans of yellow paint. How many cans of paint are in stock?
*
Step 1: Add the ones place: $6 + 4 = 10$. Write down the 0 and carry over the 1.
*
Step 2: Add the tens place plus the carry-over: $6 + 8 + 1 (\text{carry}) = 15$.
*
Calculation: $66 + 84 = 150$
Final Answer:
1) 55
2) 72
3) 167
4) 140
