Answer:

10 weeks

Explanation:

Create a system of equations demonstrating Roshaun and Keegan's savings.

  1. Roshaun: 150 + 10x
  2. Keegan: 0 + 25x

Let x equal the number of weeks they save their money.

In order to calculate how many weeks they will have the same amount of money saved, we need to set their equations equal to each other and solve for x.

  • 150 + 10x = 25x

Subtract 10x from both sides of the equation.

  • 150 = 15x

Divide both sides of the equation by 15.

  • x = 10

In 10 weeks, Roshaun and Keegan will have the same amount of money.
