Spongebob works in a burger shop. If he sells 30 burgers for $2 each and 12 large fries for $1.5. How much will Spongebob earn for the day? Give me reasons, before answering the question
Spongebob earned 30 x $2 = $60 for the burgers. He also earned 12 x $1.5 = $18 for the large fries. Therefore, Spongebob earned $60 + $18 = $78 for the day. So the final answer is 78.
