All right, so joseph has a 2 ,000 liter spa that he keeps at 38 .5 degrees celsius.
00:06
So for a, it says if the small chemicals, directions say to add 1 .5 to 2 fluid ounces every other week for every 500 gallons.
00:16
And he only has a tablespoon to measure the chemicals.
00:18
Approximately how many tablespoons should he add? so do some conversions.
00:24
We're going to have 1 liter is equal to 0 .2642 gallons.
00:29
So therefore 2 ,000 liters is going to be about 528 .4 gallons.
00:44
So with 1 .5 fluid ounces, that's going to be equal to about 0 .117 gallons.
00:56
And two fluid ounces is going to be equal to about 0 .0156 gallons.
01:06
So if he's supposed to add approximately one tablespoon of chemicals for every 500 gallons, then he should add 528 .4 divided by 500, then times 0 .117.
01:32
So this is going to be 0 .0124.
01:36
This is gallons of chemical.
01:47
So if we take that value, 0 .1 .1 .7.
01:52
0124 gallons of chemical then divide that by a gallon to teaspoon then we have 0 .0117 that's going to equal about 1 .0568 tablespoons i think i've been saying teaspoons so the whole time it was tablespoons so then using the same calculation for the two fluid ounces we have 0 .0 .0 .6 .7...
