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
The correct algebraic expression that shows how much money Jacqueline earns altogether at her two jobs is: 12b + 15c.
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
To find out how much money Jacqueline will earn altogether, we substitute b = 2 and c = 4 into the algebraic expression 12b + 15c.
12(2) + 15(4)
= 24 + 60
= 84
Therefore, Jacqueline will earn $84 altogether.
The correct algebraic expression that shows how much money Jacqueline earns altogether at her two jobs is:
12b + 15c.
To find the expression that shows the total amount of money Jacqueline earns, you need to add the earnings from both of her part-time jobs.
Let's assign variables to represent Jacqueline's earnings:
- B represents the number of hours Jacqueline works as a lab assistant at a rate of $15 per hour.
- C represents the number of hours Jacqueline works as a cashier at a rate of $12 per hour.
Now let's write the expression:
Jacqueline's earning as a lab assistant: $15 per hour * B hours = 15B
Jacqueline's earning as a cashier: $12 per hour * C hours = 12C
To calculate the total amount of money Jacqueline earns, you add the earnings of each job together:
Total earnings = Earnings as a lab assistant + Earnings as a cashier
Total earnings = 15B + 12C
Therefore, the correct algebraic expression that shows how much money Jacqueline earns altogether at her two jobs is:
15B + 12C
