Question

Nia plans to put enough money in the bank each week for 100 weeks so that the amount in the bank is always proportional to the week number. On week 8, she had $20.00. On week 12, she had $30.00. How much money will be in the savings account on week 100? $40 $66 $225 $250

Answer 1

multiply 100 by 2.5 and get 250

Answer 2

D. $250
If she has $20 on week 8, and $30 on week 12, then on week 100 she'll have $250. because 20 divided by 8 equals 2.5 same as 30 divided by 12 equals 2.5. So you multiply 100 by 2.5 and get 250.
