[Question]My mother celebrated her birthday with a total of 60 guests. Half of the guests are women, 15 are men, and the rest are children. In the middle of the celebration, 1/3 of the men and 5 children left. How many people stayed and enjoyed the birthday celebration?
[Answer]There were 60 guests / 2 = 30 women at my mother's birthday celebration. There were 30 women + 15 men = 45 men and women. So, 60 people - 45 men and women = 15 were children. Then, 15 men / 3 = 5 men left. Thus, 5 men + 5 children = 10 people left. Therefore, 60 people - 10 people = 50 people stayed and enjoyed the birthday celebration. The answer is 50.

[Question]The grocery store sells chips for $2 per packet and corn chips for $1.5 per packet. John would like to buy 15 packets of chips, and with the rest of the money he has left, buy as many packets of corn chips as he can. How many packets of corn chips could John buy if he has $45 for his entire purchase?
[Answer]John wants to buy 15 packets of chips, which will cost him 15 * 2 = $30. So John would have 45 - 30 = $15 left for the corn chips. John could buy for the rest of the money 15 / 1.5 = 10 packets of corn chips. The answer is 10.

[Question]Surfers enjoy going to the Rip Curl Myrtle Beach Surf Festival. There were 1500 surfers at the Festival on the first day, 600 more surfers on the second day than the first day, and 2/5 as many surfers on the third day as the first day. What is the average number of surfers at the Festival for the three days?
[Answer]If there were 1500 surfers on the first day, the total for the second day is 1500 surfers + 600 surfers = 2100 surfers. On the third day, the number of surfers was 2 / 5 * 1500 surfers = 600 surfers. The total number of surfers at the Festival in the three days was 1500 surfers + 2100 surfers + 600 surfers = 4200 surfers. The average number of surfers at the Beach Surf Festival for the three days is 4200 surfers / 3 days = 1400 surfers / day. The answer is 1400.

Louise has already produced 60 cakes / 2 = 30 cakes. After calculating how many cakes are left, she bakes another 30 cakes / 2 = 15 cakes. The next day, she calculates again then bakes another 15 cakes / 3 = 5 cakes. She therefore still needs to bake 60 – 30 – 15 – 5 = 10 cakes. The answer is 10.
