Over the summer, Silvio earned $380 by mowing lawns and $80 by tutoring. He wants to take an adventure vacation which costs $45 per night. What are the possible numbers of nights Silvio can sign up for if he spends only the money he earned over the summer?

Answer:

Step-by-step explanation:

First you add 380 by 80 and get 460, then divide that number by 45 and round down to get your answer 10 nights.
10 is your answer because 80+380= 460 and 10x 45 = 450 and that number is the most closest to your answer
