Equation:

Solution:

Final Answer:

Answer 1

Equation:

We start with Jason having coins from 99 countries and want to find out how many weeks it will take for him to collect coins from a total of 195 countries. He adds 4 coins each week. We can express this situation with the equation:

\[ 99 + 4w = 195 \]

where \( w \) is the number of weeks.

Solution:

1. Subtract 99 from both sides of the equation:

\[ 4w = 195 - 99 \] \[ 4w = 96 \]

2. Divide both sides by 4 to solve for \( w \):

\[ w = \frac{96}{4} \] \[ w = 24 \]

Final Answer:

It will take Jason 24 weeks to have coins from all 195 countries.
