b) $77.00
c) $78.00
d) $78.60

Answer 1

Peter still needs to save $174.90 to buy the outfit.

Step-by-step explanation:

To find out how much money Peter still needs to save, we need to subtract his expenses and the cost of the outfit from the total amount he saved.

First, let's calculate his total expenses. Peter spent $27.70 on school supplies and $45.40 on his dog, so his total expenses are $27.70 + $45.40 = $73.10.

Now, let's calculate how much money Peter still needs to save. The total amount he saved is $20.10 + $29.40 + $26.80 = $76.30. Subtracting his expenses ($73.10) and the cost of the outfit ($177.10) from the total amount he saved, we get $76.30 - $73.10 - $177.10 = -$174.90. Since the result is negative, it means Peter doesn't have enough money to buy the outfit. Therefore, he still needs to save $174.90.
