Answer:

a) $9

b) $108

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
