Answer:

41

Step-by-step explanation:

First, we need to find the sum of the ages of the first five people.

20 + 15 + 25 + 17 + 20 = 97

Then, multiply 23 by 6 to get the sum of the ages of all six people.

23 x 6 = 138

We then subtract 97 from 138 to get the age of the sixth person.

138 - 97 = 41

Zinaida [17]

Answer:

P = 150 - 25w

Step-by-step explanation:

Amount borrowed = $150

Repayment amount = $25 each week

P = amount Nancy owes

w = number of weeks

Amount Nancy owes = amount borrowed - repayment plan per week

P = 150 - 25w

During the first week of repayment: when w = 1

P = 150 - 25w

P = 150 - 25(1)

= 150 - 25

= 125

P = $125
