The mayor commissioned two artists to paint 50 murals around the city. Once the work was completed, Celina was paid $1,000 more than 4 times the amount Diego got. If the mayor paid the two a total of $50,000, how much did Diego get?
Let's think: Let d be Diego’s payment. Both artists were paid (1000 + 4 * d ) + d = 50000 dollars. This means that 5d = (50000 - 1000) dollars. Therefore Diego was paid d = 49000 / 5 = 9800 dollars.. The answer is: 9800.

Mr. Willson worked on making his furniture for 3/4 an hour on Monday. On Tuesday, he worked for half an hour. Then he worked for 2/3 an hour on Wednesday and 5/6 of an hour on Thursday. If he worked for 75 minutes on Friday, how many hours in all did he work from Monday to Friday?
Let's think: Since there are 60 minutes in an hour, then Mr. Willson worked for 60 minutes x 3 / 4 = 45 minutes on Monday. He worked for 60 minutes / 2 = 30 minutes on Tuesday. He worked for 60 minutes x 2 / 3 = 40 minutes on Wednesday. He worked for 60 minutes x 5 / 6 = 50 minutes on Thursday. So Mr. Willson worked for 45 + 30 + 40 + 50 + 75 = 240 minutes. In hours, it is equal to 240 / 60 = 4 hours.. The answer is: 4.

Jack has $43 in his piggy bank. He also gets an allowance of $10 a week. If Jack puts half of his allowance into his piggy bank every week, after 8 weeks how much will Jack have in his piggy bank?
Let's think: Jack saves $10 / 2 = $5.00 a week. Over 8 weeks Jack saves $5.00 / week x 8 weeks = $40.00. In total Jack has $43.00 + $40.00 = $83.00 dollars in his piggy bank.. The answer is: 83.

Bran's tuition fee is $90. He does a part-time job that pays him $15 per month and he has a scholarship that takes care of 30% of his tuition fee. If he needs to pay his tuition fee within 3 months, how much does Bran still need to pay?
Let's think:
Bran's scholarship pays $90 x 0.30 = $27 to his tuition fee. So, the total amount he still needs to pay is $90 - $27 = $63. And Bran will be able to earn $15 x 3 = $45 after working for 3 months. Therefore, the total amount he still needs to pay is $63 - $45 = $18.. The answer is: 18.
