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 [tex]=153[/tex] [tex]\text{lbs}[/tex]
Jon's weight loss in three successive weeks are [tex]= 4[/tex] [tex]\text{lbs}[/tex]
[tex]= 3.5[/tex] [tex]\text{lbs}[/tex]
[tex]= 2[/tex] [tex]\text{lbs}[/tex]
Total weight loss in three weeks is [tex]=4+3.5+2[/tex] [tex]\text{lbs}[/tex]
[tex]=9.5[/tex] [tex]\text{lbs}[/tex]
Jon's weight after three weeks [tex]=153-\text{weigth loss}[/tex]
[tex]=153-9.5[/tex]
[tex]143.5[/tex] [tex]\text{lbs}[/tex]
Gain in Jon's weight [tex]= 4.5[/tex] [tex]\text{lbs}[/tex]
Jon's weight after 4 weeks [tex]=143.5+\text{weight gain}[/tex]
[tex]143.5+4.5[/tex]
[tex]148[/tex] [tex]\text{lbs}[/tex]
