Final answer:
Justin will put $25 into each of the three accounts, after earning $75 in total by adding his earnings from mowing yards and washing cars.
Step-by-step explanation:
Justin earned a total of $50 mowing yards and $25 washing cars. To find how much money he earned altogether, we add these two amounts together:
- $50 (mowing yards) + $25 (washing cars) = $75 (total earned).
Next, Justin wants to divide his total earnings into 3 equal accounts. To find out how much money will go into each account, we divide the total by 3:
- $75 ÷ 3 = $25 per account.
Therefore, Justin will put $25 into each of the three accounts.
