The rules of exponents allow you to simplify expressions involving exponents. When multiplying two quantities with the same base, add exponents: xm⋅xn=xm+n x m ⋅ x n = x m + n . When dividing two quantities with the same base, subtract exponents: xmxn=xm−n x m x n = x m − n .
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>

Step-by-step explanation:
i used a calculator
but good question
Answer:
2700 - 2000 = 700 - 100 = 600 - 200 = 400 - 100 = 300
300 dollars
