[Question]: Last week, Arman worked 35 hours for 5 days at $10 per hour. This week, he will receive an increase of $0.5 per hour if he can work for 40 hours. Suppose he can work for 40 hours this week, how much will Arman receive for working two weeks?
[Answer]: Last week, Arman earned 35 hours x $10 / hour = $350. This week, Arman could earn 40 hours x $10.50 / hour = $420. So, he will receive $350 + $420 = $770 for working two weeks.
So the answer is 770.

[Question]: There are 6 forks in the cutlery drawer. There are 9 more knives than forks, and there are twice as many spoons as knives and half as many teaspoons as forks. After 2 of each cutlery is added to the drawer, how many pieces of cutlery are there in all?
[Answer]: There are 6 + 9 = 15 knives. There are 15 x 2 = 30 spoons. There are 6 / 2 = 3 teaspoons. There are 6 + 15 + 30 + 3 = 54 pieces before adding more cutlery. 2 of each 4 types of cutlery are added, and therefore 2 x 4 = 8 pieces added. In total there are 54 + 8 = 62 pieces of cutlery in the drawer.
So the answer is 62.

He needs 12 / 6 = 2 rungs per foot. So he needs 50 * 2 = 100 rungs. Each rung is 18 / 12 = 1.5 feet. So he needs 1.5 * 100 = 150 feet.
So the answer is 150.
