Question

Frank liked to buy packs of baseball cards. On 3 different days, he bought 3 packs. On 3 other days, he bought 4 packs each day. After that he split his packs with his 2 brothers. How many packs will they each have? Choose the expression that best matches this situation. [(3 x 3) + (4 x 3)] ÷ 3 [(3 x 3) + (4 x 3)] - 3 (3 x 3) + [(4 x 3) ÷ 3] [(3 x 3) + (4 x 3) ÷ 3]

Answer 1

[(3 x 3) + (4 x 3)] ÷ 3

Explanation:

Choose the expression that best matches this situation.

[(3 x 3) + (4 x 3)] ÷ 3

[(3 x 3) + (4 x 3)] - 3

(3 x 3) + [(4 x 3) ÷ 3]

[(3 x 3) + (4 x 3) ÷ 3]

On 3 different days, he bought 3 packs

= 3 × 3

= 9 packs

On 3 other days, he bought 4 packs each day.

= 4 × 3

= 12 packs

After that he split his packs with his 2 brothers

= (9 + 12) / 3

= 21 / 3

= 7 packs each for him and his two brothers

Here is the expression:

[(3 x 3) + (4 x 3)] ÷ 3

= (9 + 12) ÷ 3

= 21 / 3

= 7 packs
