Final answer:
Thaddeus has earned a total of $149.15 from raking leaves and shoveling snow. The sports camp costs $190.00, so he needs to earn another $40.85 to cover the cost.
Step-by-step explanation:
To determine how much more money Thaddeus needs to earn to pay for the sports camp, we first need to calculate the total amount he has already earned from raking leaves and shoveling snow. Thaddeus earns $63.35 from raking leaves and $85.80 from shoveling snow. We add these two amounts together to find the total amount Thaddeus has earned:
$63.35 + $85.80 = $149.15.
Next, we subtract the total amount earned from the total cost of the sports camp to find out how much more he needs to earn:
$190.00 - $149.15 = $40.85.
Therefore, Thaddeus needs to earn $40.85 more to pay for the sports camp.
