Rachel is typing a 1,500-word report. her progress is represented by the equation. 1,500 = 500 + 50t, where t is the number of minutes spent typing. if she does not take a break, how many minutes does. rachel need to type to finish her report?

To calculate this you’ll have to subtract and then divide
1500= 500+50t
1.) subtract 500 from 1500 to break down the equation
1500-500 =500+50t -500
1000= 50t
2.) now you want to get t alone... so since t is multiplied by 50, you will do the opposite and divide 50 from 1000 in order to get rid of it- which will again break down the equation
1000 /50= 50t /50
20= t

The answer is 20 minutes
Hope this helps x
