12h; $180
12 + h; $27
7(12h); $1,260
5(12h); $900
The correct expression that represents the amount of money earned in a week is 12h.
To evaluate it for h = 15, substitute h with 15 in the expression:
12(15) = 180
Therefore, the amount of money earned in a week is $180.
The expression that represents the amount of money you earn in a week is 12h.
To evaluate it for h = 15, substitute h with 15:
12(15) = 180
Therefore, for h = 15, you would earn $180 in a week.
To find the expression that represents the amount of money you earn in a week, you need to multiply your hourly wage by the number of hours you work. Since you make $12 an hour and work h hours, the expression would be 12h.
To evaluate this expression for h = 15, you simply substitute h with 15 in the expression: 12 * 15 = 180.
Therefore, the amount of money you earn in a week when working 15 hours is $180.
So, the correct expression is 12h and the evaluation for h = 15 is $180.
