Since she can arrange it in sets
let N=total number of spoons so
N mod7 1 ---->7a+1=n where a is a natural num
N mod 8 7---->8b+7=n where b is a natural num
N mod 15 3----->15c+3=n where c is a natural n
for the first set {8,15,22,29,36,43,50,57,65,71....}
for the second set {15,23,31,39,47,55,63,71,79..}
for the third set {18,33,48,63,78,....}
and find them manually but what is easier is to solve them using algebra and logic (college level)
N=840m+183 where m is zero or a postive integer
so the only N below 200 is 183
let us check
183/7=26 R 1
183/8=22 R 7
183/15=12 R 3
which means our soultion is correct
What you would do is 28.00 times 0.06 which would give you 1.68. You would do 28.00 plus 1.68, which would give you 29.68. That would be your answer. If you don't mind, may I get brainiest answer
7 days till the tank contains 14 gallons (if the day when it contains 42 gallons counts as day 0)
(11/2 , 5) sorry if im wrong im not too sure
