Chen's report will take 8 1/3 hours to complete. He has worked 3/5 of that time doing research. How long has he worked?

Sergeu [11.5K]

He has worked for 5 hours. 8 and 1/3 is equal to 24/3. Multiply that by 3/5 to get 75/15 which simplifies to 5.

Lamar works as a tutor for $12 an hour and as a waiter for $14 an hour. This month, he worked a combined total of 100 hours at h

alexdok [17]

Answer:

-2t + 1400

Step-by-step explanation:

If t represents the number of hours Lamar worked as a tutor, the number of hours he worked as a waiter can be represented by 100 - t.

Create an equation to represent the situation:

12t + 14(100 - t) = total earned

Simplify:

12t + 1400 - 14t = total earned

-2t + 1400 = total earned

So, the expression for the amount he earned is -2t + 1400
