Final answer:
To find out how much money Johnathon has remaining from his wallet, subtract the amount he put in the piggy bank and the amount used to pay his phone bill from the total amount in his wallet.
Step-by-step explanation:
To solve this problem, we need to start with the total amount of money in Johnathon's wallet, which is $189.50. He put $37.90 into a piggy bank, so the amount left in his wallet is $189.50 - $37.90 = $151.60.
Next, he used 1/4 of the remaining money to pay his phone bill. To find 1/4 of $151.60, we divide it by 4: $151.60 ÷ 4 = $37.90.
Finally, we subtract $37.90 from $151.60 to find out how much money Johnathon has remaining from his wallet: $151.60 - $37.90 = $113.70.
Therefore, the correct answer is D. $113.70.
