The school cafeteria sells two kinds of wraps: vegetarian and chicken. the vegetarian wrap costs $1.00 and the chicken wrap costs $1.80. today they made $98.80 from the 70 wraps sold. how many of the wraps sold were vegetarian?

Let x be the number of vegetable wraps and y be the number of chicken wraps. From the given above, the system of linear equations that best represent the conditions given,
                                       x + y = 70
                                       x + 1.8y = 98.80
The values of x and y are 34 and 36, respectively. Therefore, the school cafeteria sold 34 vegetable wraps.
