Q: Lucca has 100 balls and 10 percent of his balls are basketballs. Lucien has 200 balls and 20 percent of them are basketballs. In total how many basketballs do Lucca and Lucien have?
A: Lucca has 100 basketballs x (10 / 100) = 10 basketballs. Lucien has 200 basketballs x (20 / 100) = 40 basketballs. Together they have 10 basketballs + 40 basketballs = 50 basketballs. The answer is 50.

Q: Erica lives near a lake where most locals sell fish as their main source of income, earning $20 per kg of fish. She goes out fishing today and catches twice as many fish as she caught in total in the past four months. If Erica trawled 80 kg of fish in the past four months, not including today, how much money will she have earned in the past four months including today (assuming she sells all her fish)?
A: In the past four months, not including today, Erica has 80 kg * $20 / kg = $1600 worth of fish. Today, Erica trawled 80 * 2 = 160 kg of fish. Thus today's earnings are 160 kg * $20 / kg = $3200. Her total earnings are $3200 + $1600 = $4800. The answer is 4800.

First find what size Becky wears: 2 * 3 = 6. Then multiply that number by 2: 6 * 2 = 12. Then subtract 4 to find Ginger's size: 12 - 4 = 8. The answer is 8.
