Step-by-step explanation:
This is pretty much a "common sense" question. It'd be best to get rid of the dirty sanitizing water and start fresh; in other words, he should change (throw out) the dirty water and make a fresh sanitizer.
By the way, this is the Math section; next time, please choose a different section more suited to your questions.
SI =[PRT]/100
Interest = $15.62
Principal = $31
Time = 8
15.62 =[31 x R x 8]/100
15.62 x 100 = [31 x 8 x R]
[15.62 x 100] / [31 x 8] = R
1562/248 = R
6.298 = R
To the tenth
6.3 = R
Check
[31 x 6.3 x 8]/100 = 15.62
Hope that helps
Answer:
x=2.5
Step-by-step explanation:
3(17x – 6.5) = 108
Divide each side by 3
3/3(17x – 6.5) = 108/3
17x - 6.5 =36
Add 6.5 to each side
17x -6.5+6.5=36+6.5
17x = 42.5
Divide each side by 17
17x/17 = 42.5/17
x = 2.5
