given:
weekly raise= $145
to find:
an integer describing how the raise will affect her paycheck.
solution:
Let the 1st paycheck be x (integer).
Mrs. Rodger got a weekly raise of $ 145.
So after completing the 1st week she will get $ (x+145).
Similarly after completing the 2nd week she will get $ (x + 145) + $ 145.
= $ (x + 145 + 145)
= $ (x + 290)
therefore, in this way end of every week her salary will increase by $ 145.
