Question

Louise mowed a neighbor's yard to earn $25. She mowed a few more yards and earned an additional $75. She continued to mow all of the 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.

Answer 1

Since she always mowed all the yards she always earned:

`25+75`

this has to be multiplied by 5:

`5*(25+75)`

To her earnings we have to substract the money she spent, then:

`5*(5+75)-250`

Therefore the answer is C
