To determine how many Smart Phones Yoshi can buy with $314, we first need to know the price of one Smart Phone. Assuming the price of a Smart Phone is $78 (as inferred from your message), we can calculate the number Yoshi can purchase by dividing his total budget by the price of one Smart Phone:
\[ \text{Number of Smart Phones} = \frac{\text{Total Money}}{\text{Price of One Smart Phone}} = \frac{314}{78} \approx 4.02 \]
Since Yoshi can't purchase a fraction of a phone, we round down to the nearest whole number:
Yoshi can buy a maximum of 4 Smart Phones with his budget of $314.
So, the correct answer is 4 Smart Phones.
