    Part 1 :Using a variable, write an expression that describes the total amount of money earned by both boys at the end of the month.

    Let the number of lawns mowed be = x

    Earnings of Amar = 20x

    Earnings of Sang = 15x

    So total earnings are = 20x+15x

    Part 2: Amar and Sang mowed 10 lawns each by the end of the month. They need $400 for a summer trip. Do they have enough money for their trip?

    Total number of lawns mowed by each are = 10

    Amar earned = 20\times10=200

    Sang earned = 15\times10=150

    So, total money earned = 200+150 = $350

    No, they don’t have enough money for their trip. They are short of $50.
