Ms. Ervine has a basket of grapes.
If she gives 6 grapes to each of her students, she will have 2 grapes left.
If she gives 7 grapes to each of her students, she will have to buy 11 more grapes.
A) How many students does Ms. Ervine have?
B) How many grapes are in the basket?

  • Math -

    number of students : n
    number of grapes : x

    6n + 2 = x
    7n - 11 = x

    7n - 11 = 6n + 2
    n = 13
    x = 6(13)+2 = 80


    she has 13 students and 80 grapes

    check:
    6 grapes: 6(13) = 78 , she has 2 left over
    7 grapes: 7(13) = 91 , she is 11 short
    YEAH!!!
