Benny has bought a new piggy bank and wants to start saving money. In January he adds $19, then adds the same amount in February. By the end of March, he has $46. How many dollars did he add to the piggy bank in March?
Let's think: In January and February, Benny added 19 + 19 = $38 to the piggy bank. Calculating the difference between this and the total he has at the end of March shows that he saved 46 – 38 = $8 in March.. The answer is: 8.

A florist offers for sale 75 narcissus flowers and 90 chrysanthemums. Using all the flowers, how many bouquets containing 5 flowers each can he make?
Let's think: The florist can make 75 / 5 = 15 bouquets of narcissus. The florist can make 90 / 5 = 18 bouquets of chrysanthemums. The florist can make 15 + 18 = 33 bouquets in total.. The answer is: 33.

Three friends went out to watch a movie. Mitch paid for their tickets at $7 each. On the other hand, Jam paid for the 2 boxes of popcorn at $1.5 while Jay paid for the 3 cups of milk tea at $3 each. If the three of them will split the total expenses, how much should each contribute?
Let's think: Three tickets cost $7 x 3 = $21. Two boxes of popcorn cost $1.5 x 2 = $3. Three cups of milk tea cost $3 x 3 = $9. The total expenses for the their tickets and food are $21 + $3 + $9 = $33. So, each of them should contribute $33 / 3 = $11.. The answer is: 11.

Niko has bought 9 pairs of socks that cost $2 each and plans to resell them. He wants to gain 25% profit from four of the pairs of socks and $0.2 profit each for the other 5 pairs of socks. How much will his total profit be?
Let's think:
Niko will earn $2 x 25 / 100 = $0.5 profit for each of the first four pairs of socks. So, his total profit for the four pairs of socks will be $0.5 x 4 = $2. His total earnings for the 5 pairs of socks is $0.2 x 5 = $1. Therefore, his total profit will be $2 + $1 = $3.. The answer is: 3.
