3. John and Adrianne are both saving money. John has already saved $100 and plans to save $15 a week. Adrianne has already saved $40 and plans
to save $25 a week. After how many weeks of saving will both John and
Adrianne have saved the same amount of money?

It will take about 5 weeks for John and Adrianne to have saved the same amount of money,

Step-by-step explanation: For this question we can create a ratio to determine the amount of weeks it will take both John and Adrianne to have saved the same amount of money.

We know that John began with $100.

We know that Adrianne began with $40

From this point on, John's amount of money will increase by $15 and Adrianne's amount of money will increase by $25.

We can use a ratio to determine this.

AMOUNT OF MONEY : WEEKS

John-                                     Adrianne-

115:1                                        65:1

130:2                                      90:2

145:3                                      115:3

160:4                                      140:4

175:5                                      175:5
