Answer: 88
Explanation:
First use the distributive property.
4(15 + 7) can turn into 4(15) + 4(7)
Then we simplify until we get the answer.
4(15) = 60
4(7) = 28
Then it is...
60 + 28
Just add them together...
60 + 28 = 88
So the answer is 88. I hope this helps, and I hope it's not wrong, but I do not think it is.
