Nico spends $27 at the grocery store. He buys a pizza for $10. He also buys granola for $5 and 3 packages of strawberries. How much is each package of strawberries?
27 - 10 = 17
17 - 5 = 12
12/3 = 4
$4
Taylor earns $5 each time she walks her neighbors dog. She has already earned $25. Write and solve an equation to find out how many more times Taylor needs to walk the dog to earn enough to buy a bike that costs $83.
m = (83 - 25) / 5
m = 58 / 5
m = 11r3 so she would need to walk the dog 12 more times.
Franklin uses 3 eggs to make a large omelet and 2 eggs to make a small omelet. How many eggs does he need to make 5 large omelets and 4 small omelets?
large = 3x5 = 15
small = 2x4 = 8
15 + 8 = 23 eggs
Ms. Ruiz plants 14 flowers in three pots. She plants 4 flowers in one blue pot and splits the rest of the flowers equally between the two red pots. Write and solve an equation to find the number of flowers Ms. Ruiz plants in each of the two red pots.
14 - 4 = 10
10/2 = 5
5 plants in each red pot
24 rabbits and cats
Ms. Dennison packs up the books in her classroom for the summer. Each box holds 9 books. She has 24 math books and 27 science books to pack in boxes. Write and solve an equation to find how many boxes Ms. Dennison needs for the books.
b = (24 + 27) / 9
b = 51 / 9
b = 5r6
Since there are 6 books left over, Ms. Dennison needs 5 + 1 = 6 boxes
Gabriel owns 27 fiction books and 23 nonfiction books. Each shelf can hold 8 books. How many shelves does Gabriel need for all his books? Solve the problem and explain how the remainder affects your answer.
27 + 23 = 50

He will need 7 shelves for all his books.
Dwayne has 3 erasers. Joey has 2 times as many erasers as Dwayne. Maria has 5 more erasers than Joey. Which equations can be used to find how many erasers Maria has? Choose ALL the correct answers.
a. e = (3 x 2) + 5
b. e = 3 x (2 + 5)
c. e = (5 + 2) x 3
d. e = 5 + (2 x 3)
e. e = (3 + 5) x 2
a and d
Tiana sells 47 boxes of oranges for a fundraiser. Tim sells 12 fewer boxes than Tiana. How many more boxes of oranges does Tim need to sell in order to sell 60 boxes?
