Answer:
144 miles
Step-by-step explanation:
37.5 = initial rate
44.9 = slope/rate
In problems like these, just use y = initial rate + rate(variable)
In this case, the answer would be y = 37.5 + 44.9h

<span>Using what's given, you'd have $2800 = p x 0.04 x 3.5. </span>
<span>We don't know the principle so you'd leave the variable there and convert 4% interest to 0.04. Solve by getting 2800 = p(0.14) then divide each side by 0.14 and get p=20,000. So your principle, or the amount deposited, should be $20000. You can solve by plugging in your answer (20000 x 0.04 x 3.5 = 2800)
</span>Interest = Principal * rate * time
<span>2800 = x * 4% * 3.5 </span>
<span>2800/(4% *3.5) = x </span>
<span>20000 = x
