[Question]: Nedy can eat 8 packs of crackers from Monday to Thursday. If Nedy ate twice the amount on Friday, how many crackers did Nedy eat in all?
[Answer]: Nedy can eat 8 x 4 = 32 crackers from Monday to Thursday. He can eat 8 x 2 = 16 packs of crackers on Friday. Therefore, Nedy ate 32 + 16 = 48 crackers in all.

[Question]: A developer was buying land. He bought 4 acres at $1,863 per acre. He then split the land he purchased into 9 lots. How much should he sell each lot for just to break even?
[Answer]: His purchase cost is 4 acres * $1863 = $7452. He divided the land into 9 plots, so the price per lot would be $7452 / 9 = $828.
So the answer is 828.

[Question]: Jackson and Brandon both invest $500 in the stock market. Jackson's investment quadruples in value, while Brandon's is reduced to 20% of the initial value. How much more money does Jackson have than Brandon now?
[Answer]:
First find the end value of Jackson's investment: $500 * 4 = $2000. Then find the end value of Brandon's investment: 20% * $500 = $100. Then subtract the value of Brandon's investment from the value of Jackson's investment to find the difference: $2000 - $100 = $1900.
So the answer is 1900.
