Answer:
10(3p+1)
Explanation:
10 goes into 30 3 times and 10 once, so what you have to do is divide 30 by 10, which I just said is 3 and 10 divided by 10, which is 1. After that you set up your problem by putting 10 on the outside of the parentheses and 3p as the first on the outside because it shows up first and 1 as the second because it shows up second.
