Answer 2

Jane spent $30 to buy materials to make bracelets. She sold the bracelets using two pricing options. Option A is 5 bracelets for $6, and Option B is 3 bracelets for $4. Jane made three sales with Option A, and six sales with Option B. Which numerical expression results in Jane’s profit? How much was Jane’s profit?(1 point)

answers:
*(3x6+ 6x4)- 30 janes profit was 12
*(3⋅6⋅5+6⋅4⋅3)−30; Jane’s profit was $132.
*(3⋅6+6⋅4)+30; Jane’s profit was $72.
*30−(3⋅6+6⋅4); Jane did not make any profit.

Answer 3

[AI-generated answer — Bot GPT 3.5]

The correct numerical expression that results in Jane's profit is (3x6 + 6x4) - 30.

Jane's profit can be calculated as follows:
3x6 = 18 (profit from Option A sales)
6x4 = 24 (profit from Option B sales)
18 + 24 = 42 (total profit)
42 - 30 = 12 (Jane's profit)

Therefore, Jane's profit was $12.

The correct answer is: (3x6 + 6x4) - 30; Jane's profit was $12.

Answer 4

Which of the following shows the correct pairing of a property of operations and its example?(1 point)

Responses

2(a+3) = 2a+6; Commutative Property
2 times open paren A plus 3 close paren is equal to 2 A plus 6 ; Commutative Property

2a + 3b = 3b + 2a; Commutative Property
2 A plus 3 b is equal to 3 b plus 2 A ; Commutative Property

2a +3b = 3b + 2a; Distributive Property
2 A plus 3 b is equal to 3 b plus 2 A ; Distributive Property

2(a+3) = 2a+6; Associative Property

Answer 5
