You must use ALGEBRA in order to solve this problem.
Step 1. T= Tray's age and J= Jan's age Step 2. (T*2)-3 and T+J=30 Step 3. Tray must be 11 because and Jan must be 19, it never said that Tray is OLDER. Step 4. Recheck----- (11*2)-3=19
Sorry, I don't explain too well, I am used to doing it in my head... Hope this helps!!! :D
Depending on the wage so im just gonna use an example to help you so lets say the wage is $15 per hour you would multiply 15 by 4 and thers your answer, please state the wage
