Answer this question:For a New Year’s Eve appetizer, Alex is serving caviar with potato chips and creme fraiche. He buys 3 individual bags of potato chips for $1.00 each and dollops each chip with some creme fraiche that costs $5.00 and then the $73.00 caviar. This appetizer will serve 3 people. How much will this appetizer cost per person?
He buys 3 bags of potato chips for $1.00 each so that’s 3 * 1 = $3.00. The chips are $3.00, the creme fraiche is $5.00 and the caviar is $73.00 for a total of 3 + 5 + 73 = $81.00. The appetizer costs $81.00 and will serve 3 people so it will cost 81 / 3 = $27.00 per person.

Answer this question:A farmer harvested 250 potatoes. He bundled them in twenty-five's and sold each bundle for $1.90. He also harvested 320 carrots and bundled them in twenty's and sold each bundle for $2. If the farmer sold all his harvested crops, how much did he get in all?
There are 250 / 25 = 10 bundles of potatoes. So, 20 bundles of potatoes amount to $1.9 x 10 = $19. There are 320 / 20 = 16 bundles of carrots. So, 16 bundles of carrots amount to $2 x 16 = $32. Hence, the farmer got $19 + $32 = $51 in all.
The answer is 51.
