To break it down, there are 8 slices of pizza to share and 6 people. So, automatically each person would get at least one slice of pizza. Now fo the remaining 2 slices all we need to do is simplify 2/6 (because there are 2 slices and 6 people) and once simplified, you have 1/3. So now, you dd the 2 numbers together to get 1 1/3.
736 total - travel insurance cost per person 19x4=76-736=660:4=165 so x represent 165+travel insurance for 19 =184 total per person.x=184 hope it helps!
