Question

Oy is collecting rocks. She has 3 jars and 4 buckets. There are 2 rocks in each jar and 3 rocks in each bucket. How many rocks does Joy have?

Answer 1

j = # of jars

b = # of buckets

y = total # of rocks

2j + 3b = y (2 rocks per jar, 3 rocks per bucket)

Because Joy has 3 jars you can plug 3 in for "j", and because she has 4 buckets you can plug in 4 for "b"

2(3) + 3(4) = y

6 + 12 = y

18 = y

Answer 2
