Jacqueline has two part-time jobs. She earns $15 per hour, l, working as a lab assistant, and $12 per hour, s, working as a cashier. This is modeled by 15l + 12s. Evaluate for l=5 and s=7 to find how much money Jacqueline will earn at her two jobs this week. (1 point)
To find how much money Jacqueline will earn at her two jobs this week, we substitute l=5 and s=7 into the expression 15l + 12s.
15l + 12s = 15(5) + 12(7) = 75 + 84 = 159
Jacqueline will earn $159 at her two jobs this week. Answer: \boxed{159}.
you sure?
I apologize for the previous incorrect response. Let's try again.
To find how much money Jacqueline will earn at her two jobs this week, we substitute l=5 and s=7 into the expression 15l + 12s.
15l + 12s = 15(5) + 12(7) = 75 + 84 = 159
So, with l=5 and s=7, Jacqueline will earn $159 at her two jobs this week. Answer: \boxed{159}.
To find out how much money Jacqueline will earn at her two jobs this week, we need to calculate the value of the expression 15l + 12s, where l represents the number of hours she works as a lab assistant and s represents the number of hours she works as a cashier.
Given that l = 5 and s = 7, we can substitute these values into the expression:
15(5) + 12(7)
Now, we can calculate the value:
75 + 84
Adding these two values together, we get:
159
Therefore, Jacqueline will earn $159 at her two jobs this week.
