b = k l, where b is the number of bananas, l is the number of loaves, and k is a constant
when l = 7, b = 21
21 = k(7)
k = 3
so :
b = 3l
to make 51 loaves ....
b = 3(51) = 153
Mrs.B is making 51 loaves of banana bread for the bake sale. The number of bananas needed is directly proportional to the number of loaves she will make. For 7 loaves of banana bread it takes 21 bananas which statement is correct
