Q: A department store offers a 10% discount for the amount exceeding $100 of the customer's total charge. Jaco bought a pair of shoes for $74; 2 pairs of socks that cost $2 per pair; a bag that costs $42. How much will Jaco pay for those items?
A: Two pairs of socks cost $2 x 2 = $4. Jaco's total charge is $74 + $4 + $42 = $120. The amount that exceeds $100 is $120 - $100 = $20. So, Jaco has $20 x 10 / 100 = $2 discount. Therefore, Jaco will pay $120 - $2 = $118 for those items. The answer is 118.
Question: Ann, Becky, and Julia are working at a pharmacy, every day for 8 hours. Each of them is providing service to 7 customers per hour. One day Julia had to finish her work earlier, so she was working only for 6 hours. How many customers did all three of these women serve that day in total?
Answer: Ann and Becky have worked for 8 hours each, so both of them worked for 2 people * 8 hours / person = 16 hours. All three of them, including Julia, were working for 16 hours + 6 hours = 22 hours. So in total, they all have served 7 customers / hour * 22 hours = 154 customers in one day. The answer is 154.

Q: Tim and Donna will celebrate their 20th wedding anniversary in 2025. They started dating 3 years before they got married and met 2 years before that. When did they meet?
A: They'll celebrate their 20th wedding anniversary in 2025 which means they got married in 2025 - 20 = 2005. They started dating 3 years before they got married in 2005 which means they started dating in 2005 - 3 = 2002. And they met 2 years before they started dating which means they met in 2002 - 2 = 2000. The answer is 2000.
