You should probably start by changing the fractions into decimals. then you multiply the decimal of 1 1/4 by the decimal of 3 1/2. Next you multiply the decimal of 1 3/4 by the decimal of 3 1/2. then you find the difference and that's your answer, alternatively you could leave them as fractions, do the same thing and then change it into a decimal.
Hope this helps :)

Step-by-step explanation:
From the information you have given me, I would say Kimmy has $<span>468.98 </span>dollars in her bank account.
Does she get more money during the other months, just as she had gotten 5 times as much as she had in a 3 month span? (From june to september.) All I could tell was her money was multiplied by 5, then you add $87.83 more into her account.
Please check my math if you want to be sure.
$76.23 * 5 = $381.15
$381.15 + 87.83 = 468.98
