22. Bradley and Ryan are having a contest to see who can collect the most bumper stickers. Bradley started with 23 bumper stickers and plans to add 4 each month.

Question

Ryan has 9 bumper stickers and plans to add 6 each month. After how many months will they have the same number of bumper stickers? (1 point)
• 10 months
• 2 months |
• 7 months
• 51 months.

Answer 1

To find the number of months it will take for Bradley and Ryan to have the same number of bumper stickers, we can set up an equation.

Let x be the number of months it takes for them to have the same number of bumper stickers.

Bradley: 23 + 4x
Ryan: 9 + 6x

Setting them equal to each other:

23 + 4x = 9 + 6x

Subtract 9 from both sides:

14 + 4x = 6x

Subtract 4x from both sides:

14 = 2x

Divide by 2:

x = 7

After 7 months, Bradley and Ryan will have the same number of bumper stickers.

Therefore, the answer is 7 months.
