Hi there! :)
<u>Answer:</u>
20% of the money she saved last year was saved during the month of January.
Step-by-step explanation:
Marie saved $3,000 last year.
She saved $600 in the month of January.
SO, Marie saved:
In order to answer your question, you'll need to use the cross product method (because you want to have a percentage, which is on 100 and not on 3,000 like we have right now):
<u>(100 × 600)</u> ÷ 3,000 = x
<u>60,000 ÷ 3,000</u> = x
<u>20 = x</u>
There you go! I really hope this helped, if there's anything just let me know! :)
