Answer: He bought 4 cupcakes and 12 donuts

Step-by-step explanation:

He bought three times as many donuts as cupcakes so we could represent that by the equation  d= 3c  where d is donuts and c is the cupcakes.

If cupcakes also cost 50 cent and donuts cost a dollar each and he spent a total of 10 dollars then we could also represent that by the equation  

0.50d + 1c = 10    

Now combine use the two equations and solve for d and c

d= 3c

0.50d + 1c =10    substitute d in the first equation into the second equation.

0.50(3c) + 1c =10

1.5c + 1c =10

2.5c = 10

  c=  4  

In this case he bought a total of 4 cupcakes and to find the total of donuts that he bought we multiply that by 3 because he bought three times as much as that.

d= 3 * 4

d = 12

(20 points) please give me motivation to study and study tips or test taking tips for finals. it would be greatly appreciated.
Daniel [21]

Answer: Think about graduating. Think about never having to take the courses again. You're almost at the finish line! It'll be worth it. You've worked hard all year for this. You can do it!

Study tips: I would recommend Quizlet! They have a section that generates study games. It's a lot more fun than normal studying. It's also a good idea to make a goal for yourself. Try to make a challenge of achieving a certain score! By the time you accomplish said score, you'll find that you've learned a lot. Another tip is to make sure you take breaks. If you work too long without giving yourself a break, it will become harder to focus and your brain will become tired. Just don't get too distracted! set yourself an alarm during break times to help you stay on task. If you become frustrated with a certain subject or task, take a break from that task. Use this time as an opportunity to work on another subject. You can begin working on the first subject again once you feel refreshed. A lot of this may sound redundant, but hopefully it will help at least a little bit. Good luck!
