Jessica has a bag with 80 marbles and every 2 months she loses 5 marbles. Write an equation that models the situation. How many marbles are left after 10 months?

Respuesta :

60 are left because If there she loses 5 every 2 months and you add 2 everey time until you get to 10 that makes 20 that she lost so 80-20 is 60:)
