Question: As a freelancer, Baylor is paid for every finished work of a client he does on a freelance marketplace. Currently, he has $4000 on his dashboard from previous work done. He is currently working for three clients, with the first client paying him half the amount of money he currently has on his dashboard once the job is done. The second client will pay him 2/5 times more money than the first client once Baylor finishes his work. The third client will pay him twice the amount of money the first and second clients pay him together once he finishes the job. How much money will Baylor have in his dashboard after all the clients pay him for his work?
Answer with step-by-step thinking: The first client will pay Baylor 1 / 2 * $4000 = $2000. The second client will pay Baylor 2 / 5 times more money than the first client, a total of 2 / 5 * $2000 = $800. The total amount of money the second client will pay Baylor once the job is done is $2000 + $800 = $2800. The total amount of money the first and the second client will pay Baylor after their work is finished is $2800 + $2000 = $4800. The third client will pay him twice the amount of money the first and second clients pay him together, a total of 2 * $4800 = $9600. Together, the three clients will pay Baylor $9600 + $4800 = $14400 once he finishes their jobs. In his dashboard, Baylor will have $14400 + $4000 = $18400.
So the answer is 18400.


Question: Miriam is trying to exercise more and figures if she counts her exercises it will be encouraging to see her numbers go up. On Monday she does 5 push-ups. On Tuesday she does 7 push-ups. On Wednesday she does twice as many push-ups as the day before. On Thursday she does half the number of total pushups she already did that week. Finally, on Friday she does as many pushups as the total number she did over the previous four days. How many pushups does Miriam do on Friday?
Answer with step-by-step thinking:
On Monday Miriam does 5 push - ups + 7 push - ups on Tuesday = 12 push - ups on both days. On Wednesday she does twice as many push - ups as she did on Tuesday, 7 x 2 = 14 push - ups on Wednesday. Over the first 3 days, she did a total of 14 + 12 = 26 pushups. On Thursday Miriam did 1 / 2 the same number of total pushups she had already done that week, so she did 1 / 2 x 26 = 13 pushups on Thursday. On Friday she does as many push - ups as the total of what she had done over the previous four days, so she did 5 + 7 + 14 + 13 = 39 push - ups on Friday.
So the answer is 39.
