Kiri walks : 4 km per week

0.5 × 5 + 0.75 × 2 = 2.5 + 1.5 = 4 km per week.

WHY?

Because 0.55 is close to 0.5 and 1.4 is closer to 1.5

Answer:

Cost of each ticket per person = $42

For groups of up to 8 people, the cost per ticket decreases by $3 for each person in the group.

Marco's ticket cost $30.

This means he paid 42-30=12 dollars less.

Now when there are 8 members, the cost decreases by $3.

So, $12 will decrease, when there will be members

I hope this helps! Have an awesome day!
