Answer:
148 lbs
Step-by-step explanation:
Given: Jon's weight loss for each week of the month is 4 lbs., 3.5 lbs. and 2 lbs. He gained 4.5 lbs. the last week.
To Find: If Jon originally weighted 153 lbs., how much does he weigh now
Solution:
Jon's original weight \(=153\) \(\text{lbs}\)
Jon's weight loss in three successive weeks are \(= 4\) \(\text{lbs}\)
\(= 3.5\) \(\text{lbs}\)
\(= 2\) \(\text{lbs}\)
Total weight loss in three weeks is \(=4+3.5+2\) \(\text{lbs}\)
\(=9.5\) \(\text{lbs}\)
Jon's weight after three weeks \(=153-\text{weigth loss}\)
\(=153-9.5\)
\(143.5\) \(\text{lbs}\)
Gain in Jon's weight \(= 4.5\) \(\text{lbs}\)
Jon's weight after 4 weeks \(=143.5+\text{weight gain}\)
\(143.5+4.5\)
\(148\) \(\text{lbs}\)
Jon weighs \(148\) \(\text{lbs}\) now.
