Frank has x stamps and chris has 8 more than 7 times the number of stamps frank has. how many stamps do frank and chris have in total?

a=8x
b=7x+8
c=8x+7
d=8x+8
e=56x+7

I believe the correct answer is D. 8x+8;
Because Frank has X and Chris has 8 + 7x (7 times Frank's number) and adding Frank's number (x) to 8 + 7x makes it 8 + 8x.

Hope I could help!
