Answer: packages of buns: 100
               packages of patties: 67
                jars of pickles: 133
(100,67,133)
Step-by-step explanation: packages of buns: B
                                             packages of patties: P
                                             jars of pickles: J
B:P:J = 3:2:4
B + P + J = 300
Let x be the number we must multiply the numbers to obtain the quantity and keep the ratio.
Bx + Px + Jx = 300
3x + 2x + 4x = 300
x = 300/9
So,
3.300/9 = 100
2.300/9 = 66.6666
4.300/9 = 133.333
As we cannot buy 0.666 or 0.33 of patties and pickles, we round up
So:  packages of buns: 100
               packages of patties: 67
                jars of pickles: 133
