Mary and Bill both are saving money. Mary already has $30 and is able to save $5.50 every week. Bill already has $45 and is able to save $4.25 every week. When will Mary and Bill have the same amount of money?

12 weeks

Step-by-step explanation:

Let the week that both of them will have thesame amount of money be represented by x.

Since Mary already has $30 and is able to save $5.50 every week, this will be denoted as: 30 + 5.50x

Since Bill already has $45 and is able to save $4.25 every week, this will be debited by 45 + 4.25x. Then we'll equate both equations and this will be:

30 + 5.50x = 45 + 4.25x

5.50x - 4.25x = 45 - 30

1.25x = 15

x = 15/1.25

x = 12

They'll have thesame amount of money in 12 weeks.

unpaid balance is : $149.99-$50 = $99.99 new balance = 149.99+2.62-50 = $102.61 finance charge = 99.99- 0.21/12= $1.75 new balance = 99.99+1.75 = $101.74 average daily balance method average daily balance= 3399.70/30 = $113.32 finance charge = $ 0.21/12ă—113.32 = $1.98 new balance = $149.99-50+1.98 = $101.97

c. (3,2,6) is the answer.
