Well, she drove 200 miles, at a pay of $0.60 per mile travelled.
<span>200 * 0.6 = 120 </span>
<span>She got payed $120 for her 200 miles traveled. </span>
<span>Since she gets payed $50 per day, and she got paid $1500 for her food and lodging, she traveled for 30 days as 1500/50 = 30 (Part C answer) </span>
<span>If you were to determine her total pay: </span>
<span>Using variables x for: number of days spent on trip </span>
<span>Y: number of miles traveled. </span>
<span>Total pay = 50x + 0.6y </span>
<span>If you'd rather have only the equation for the number of days spent on her trip: </span>
<span>X = (1620- 0.6(200))/50. (Part A answer) </span>
<span>Solving for x: </span>
<span>X = (1620 - 0.6(200))/50 </span>
<span>X = (1620 - 120)/50 </span>
<span>X = (1500)/50 </span>
<span>X = 30 (Part B answer)</span>

5a-5=7+2a -- we need to isolate a. Subtract 2a from both sides
3a-5=7 -- add 5 to both sides
3a=12 -- divide by 3
a=4
