A restaurant sells slices for $2 and calzones for $3. On Monday, a total of 54 slices and calzones were sold, and the cashier collected a total of $120 from sales of slices and calzones. Let x represent the number of slices and y represent the number of calzones. Which system of equations represents the situation? Select the correct answer below: O O O O O X = x+1.5y = -* 1 x+1.5y X = = x+1.5y = % x-1.5y X x+1.5y = = 54+y 60 54-y 60 54-y 60 54-y 60 = 54-y = -60
