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.
To find out how much money Jacqueline will earn at her two jobs this week, we need to evaluate the expression 15l + 12s with l = 5 and s = 7.
Substituting the values, we get:
15(5) + 12(7) = 75 + 84 = 159
Therefore, Jacqueline will earn $159 at her two jobs this week.
To find out how much money Jacqueline will earn at her two jobs this week, plug in the values of l=5 and s=7 into the expression 15l+12s.
Step 1: Substitute l=5 and s=7 into the expression.
15 * 5 + 12 * 7
Step 2: Multiply the values.
75 + 84
Step 3: Add the results.
159
Therefore, Jacqueline will earn $159 at her two jobs this week.
To find how much money Jacqueline will earn at her two jobs this week, we can substitute the given values of l=5 and s=7 into the expression 15l + 12s.
So, we have:
15(5) + 12(7)
To evaluate this expression, we perform the multiplication first:
75 + 84
Then, we add the two numbers:
159
Therefore, Jacqueline will earn $159 at her two jobs this week.
