Clara bought a bracelet for $15 from Shein. She also purchased 3 pairs of earrings for $5 each. How much money did Clara spend in total?

Back

15 + 3 x 5

Answer explanation

Clara spent $12 on a necklace and 4 hair clips at $2 each. The total cost for the clips is 4 x 2 = 8. Therefore, the total amount spent is 12 + 8, which is represented by the expression 12 + 4 x 2.

Bunny baked 10 carrot muffins for herself. She then baked 20 more carrot muffins and shared them equally with 4 friends. How many carrot muffins does Bunny have now?

Back

10 + 20 ÷ 5

Answer explanation

Bunny starts with 7 cookies and makes 16 more. She splits the 16 cookies among herself and 3 friends, totaling 4 people. Each gets 16 ÷ 4 = 4 cookies. Thus, Bunny has 7 + 4 = 11 cookies, represented by 7 + 16 ÷ 4.

Front

Evaluate the expression: 36 ÷ 4 x 6

Back

54

Answer explanation

To evaluate 24 ÷ 3 x 8, follow the order of operations (PEMDAS). First, divide: 24 ÷ 3 = 8. Then, multiply: 8 x 8 = 64. Thus, the correct answer is 64.

Front

Evaluate the expression: 36 + 18 ÷ 3

Back

42

Answer explanation

To evaluate 44 - 24 ÷ 4, first perform the division: 24 ÷ 4 = 6. Then subtract: 44 - 6 = 38. Thus, the correct answer is 38.

Front

Expression: 5 more than the product of 7 and 4.

Back

7 x 4 + 5

Answer explanation

The phrase '8 less than the product of 9 and 3' translates to '9 x 3 - 8'. Evaluating this gives 27 - 8 = 19, making '9 x 3 - 8' the correct expression.

Front

(20 - 8) ÷ 4

Back

3

Answer explanation

The correct expression is (17 - 5) ÷ 3. First, subtract 5 from 17 to get 12, then divide 12 by 3, resulting in 4.

Front

56 ÷ 8 + 4

Back

4 more than the quotient of 56 and 8

Answer explanation

The expression 49 ÷ 7 + 3 can be interpreted as '3 more than the quotient of 49 and 7', which matches the correct choice. The other options do not accurately represent the operations in the expression.

Front

Which word phrase represents the numerical expression (15 + 5) x 3?

Back

3 times the sum of 15 and 5

Answer explanation

The expression (28 - 8) x 4 means to first find the difference of 28 and 8, then multiply that result by 4. Thus, it is correctly represented by '4 times the difference of 28 and 8'.

Front

Calculate the result of: 36 ÷ 4 + 7

Back

16

Answer explanation

To evaluate 45 ÷ 5 + 4, first divide: 45 ÷ 5 = 9. Then add 4: 9 + 4 = 13. Thus, the correct answer is 13.
