Answer:
C = 0.75(n/2)
Step-by-step explanation:
For each pair of signs, $0.75 is needed for the posterboard.
C = 0.75(n/2)
This can be simplified to ...
C = 0.375n . . . . for n an even number
__
If posterboard only comes in the size given, then the more technically correct answer is ...
C = 0.75·ceiling(n/2)
Answer:
55
Step-by-step explanation:
Just add them together. 1+2=3; 3+3=6; 6+4=10; 10+5=15; 15+6=21; 21+7=28; 28+8=36; 36+9=45; 45+10=55.
The factors are all the possible things you would multiply to get the number. So finding the 2 middle numbers, in this case is 21 and 28 and multiplying them, you get 588. If you're not sure if that's right, take the number on the left or right of the 2 middle numbers, 14 and 42. The product of these 2 numbers are also 588. So your number is 588.
