Answer 1

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.

Answer 2

You have to add the weight he loss then subtract it from 153
