To determine how many weeks (w) it will take Jason to collect coins from all 195 countries, we should first set up the correct equation.
Jason currently has coins from 99 countries and is adding coins from 4 new countries each week. Therefore, the equation that represents this situation is:
A) 99 + 4w = 195
Now, let's solve for w:
-
Start with the equation: \[ 99 + 4w = 195 \]
-
Subtract 99 from both sides: \[ 4w = 195 - 99 \] \[ 4w = 96 \]
-
Divide both sides by 4: \[ w = \frac{96}{4} \] \[ w = 24 \]
So, it will take Jason 24 weeks to collect coins from all 195 countries.
Now, let's evaluate the options given:
A) \( w = 2.4 \) - Incorrect
B) \( w = 24 \) - Correct
C) \( w = 20 \) - Incorrect
D) \( w = -22 \) - Incorrect
Final Answer: It will take Jason 24 weeks to have coins from all the countries.
