Question

Chris starts with $100 in his account and saves $20 per month, represented by the equation: $100 + $20x. How long will it take him to save $300?

Answer 1

It will take Chris 10 months to save $300.

Step-by-step explanation:

To determine how long it will take Chris to save $300, we can set up an equation using the equation $100 + $20x = $300, where x represents the number of months. To solve for x, we first subtract $100 from both sides of the equation to isolate $20x. This gives us $20x = $200.

To solve for x, we divide both sides of the equation by $20. This gives us x = 10. Therefore, it will take Chris 10 months to save $300.
