To find out how many weeks it will take Jason to collect coins from all 195 countries, we can set up the following equation.
- Current number of countries: 99
- Target number of countries: 195
- Number of new countries added per week: 4
First, we find out how many more countries Jason needs to collect coins from:
\[ \text{Countries needed} = \text{Target} - \text{Current} = 195 - 99 = 96 \]
Next, we can set up the equation for the number of weeks \( w \) it will take to collect these additional countries at the rate of 4 per week:
\[ 4w = 96 \]
Now, solve for \( w \):
\[ w = \frac{96}{4} = 24 \]
Equation:
\[ 4w = 96 \]
Solution:
\[ w = 24 \]
Final Answer:
It will take Jason \( 24 \) weeks to have coins from all 195 countries.
