b) $108

Step-by-step explanation:

Kindly find attached to the answer, the picture of containing showing the amount of money Natalie still owes her parents at the end of every two weeks for the first eight weeks.

From the table

Week 0 = $180

Week 2 = $162

Weeks 4 = $144

Week 6 = $126

Week 8 = $108

a) How much does Natalie pay her parents each week?

We can calculate the difference for 2 weeks

Week 0 - Week 2

= $180 - $162

= $18

Hence, Natalie pays $18 every 2 weeks.

The amount she pays every week

= $18÷ 2

= $9

b) What is the initial amount Natalie still owes?

After paying $9 per week, the amount Natalie still owes after 8 weeks is

=$180 - $9 × 8

= $180 - $72

= $108

Natalie still owes her parents $108
