Part A) Jacqueline has two part-time jobs. She earns $15 per hour, b, working as a lab assistant, and $12 per hour, c, working as a cashier. Which algebraic expression below shows how much money Jacqueline earns altogether at her two jobs?(1 point)
Responses
12b + 15c
12 b + 15 c
15b - 12c
15 b - 12 c
15b + 12
15 b + 12
15b + 12c
15 b + 12 c
Question 2
Part B) If Jacqueline works 2 hours working as a lab assistant and 4 hours as a cashier, how much money will she earn altogether? b = 2 and c = 4(1 point)
if your done with the test say the answers then!
To simplify by combining like terms, we group the variables with the same letter:
5a − 9a + b + 6b - 8c + 3c
Then, we combine their coefficients:
(5a - 9a) + (b + 6b) + (-8c + 3c)
Resulting in:
-4a + 7b - 5c
then what is it
Part A) The correct algebraic expression that shows how much money Jacqueline earns altogether at her two jobs is 12b + 15c.
Part B) If Jacqueline works 2 hours as a lab assistant and 4 hours as a cashier, plugging in b = 2 and c = 4 into the expression, she will earn:
12(2) + 15(4) = 24 + 60 = $84 altogether.
Simplify by combining like terms: 5a − 8c + b + 3c −9a + 6b

-2m + 3t - 2m - t
4m - 2t + 2m - t
The correct match is:
3m + t - m + 2t = 2m + 3t
