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?

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!!!
