How many large pumpkins?

Question

The pumpkin patch has large pumpkins and regular pumpkins for sale. There are 20% fewer large pumpkins than regular pumpkins. Altogether, there are 198 pumpkins for sale. How many large pumpkins and how many regular pumpkins are there?

Answer 1

r=# of regular pumpkins

20%=20/100=1/5=0.2

there are 20% fewer large pumpkins or the number of large pumpkins is 80% of the number of regular pumpkins

80%=80/100=4/5=0.8

0.8r=# of large pumpkins

r+0.8r=198

1.8r=198

18r=1980

r=1980/18

r=110 regular pumpkins

80% of 110=0.8*110=88 large pumpkins
