Algebra Question
posted by Dab on .
Luisa ran 3 miles on the 3rd day of a month, and she repeated her run every 4 days for the rest of the month. What equation describes the sequence of days of that month that Luisa ran?
 I have no idea how to begin this.

Does the month have 30 days?
She ran on the 3rd, 7th, 11th, 15th, 19th, 23rd, 27th and 31st? 
3+((x3)/4)*3=Total Miles
Fill in X with number of days in month 
3+((x3)/4)*3=Total Miles
Fill in X with number of days in month 
OMG, I need help on this question too...
It asks for sequence of days not miles though...
