Answer:
4(3+7)
Explanation:
The total number of hours Tony worked for both weeks is 12 + 28 = 40.
To find the equivalent expression that represents the total number of hours worked in relation to the number of days worked each week, we need to divide 40 by the total number of days worked, which is 10 (2 workdays per week).
So the expression we need is:
40/10 = 4(3+7)
Therefore, the answer is 4(3+7).
