Answer: 19 days
Step-by-step explanation:
305-115=190
190 divided by 10= 19
18%=0.18
380×0.18=68.4 increase
380+68.4=448.4
the easier way is to think 1 times any number is the same number so 380(1+0.18)=448.4 (just like adding tax to the price of something to see how much you'll actually pay)
Answer:575 and 1 extra tile
Step-by-step explanation:if the total tiles is 5,176 which will be used in 9 floors .We will divide the total tiles by the floors .Therefore we will get 5176 /9 =575.111
Therefore each floor will have 575 tiles
To get the remaining tiles
575*9 = 5175 which gives us a remainder of 1 tile when you subtract the total 5176 -5175 =1
B) 36
To figure this out you need to average the numbers. To average them you add them all up and divide by how many are there.
(60+30+20)/3
(90+20)/3
110/3
36
