ANSWER: -252
HOW TO GET IT:
Simply follow PEMDAS. Solve each exponent first, then do the rest.
You'll need to write your question a bit clearer. It's difficult to understand because a lot of it seems jumbled together.
63 x 38 = 2394
63 x 10 = 630
600 x 3 = 1800
30 x 3 = 90
1800 + 90 = 1890
63 x 2 = 126
630 - 126 = 504
1890 + 504 = 2394
Estimate 95 to 90 and 8 to 10
now multiply 90 and 10 = 900
You can serve 15 people with 10 cups. (Work shown on picture.) hope this helps! Have a great day/night!
