2 Answers
150 pounds
Explanation:
We require to calculate how many glasses of water Kelby drank per day.
Since there are 7 days in 1 week, if we divide 168 by 7 this will give us how much he drank each day.
#rArr168÷7=24# We are told he has to drink 8 lasses each day for every 50 pounds of weight.
Since
#24=3xx8# then his weight is approximately
#3xx50=150" pounds"#
150 lb
Explanation:
'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Let unit of weight in pounds be lb
Let unit of day be d
Let unit of glasses be g
8 glasses per 50 lb
This configuration of the units of measurement will not give what we need so turn the whole thing upside down giving:
'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
168 glasses in 1 week
1 week = 7 days
