Question

Louise earned
\[\$25\] by mowing a neighbor's yard. She mowed a few more yards and earned an additional
\[\$75\]. She mowed all of the same yards each week for a total of
\[5\] weeks, earning money at the same rate. At the end of the
\[5\] weeks, she spent
\[\$250\].
Which numerical expression shows the amount of money Louise has left?

Answer 1

5*(25 + 75) - 250

(Which equals 5*100 - 250 = 500 - 250 = $250.)
