Question

Ozzie's Mother bought an assortment of greeting cards while she was at the bookstore. She bought twice as many birthday cards as anniversary cards. She bought 2 fewer anniversary cards than general greetings cards, but 2 more anniversary cards than get well cards. If she bought 2 get well cards, how many cards did she buy in all?

Answer 1

So it's:
b=2a
a=g-2
a=gw+2

There are 2 gw cards, so there must be 4 a cards. If there are 4 a cards, there must be 8b cards and 2 g cards.

8+4+2+2=16
So 16 is the answer.

Answer 2

Make a chart

Get well - 2
Anniversary - 4
General Greeting- 6
Anniversary - 8

2+4+6+8 = 20
20 total cards

Answer 3

Answer is 20

2 get well cards
4 anniversary cards
6 greeting cards
8 birthday cards
