Question 1153252
<br>
The answer by tutor @josgarithmetic is wrong.<br>
The old rate was 20 cars per day; the new rate is 70 cars per day.<br>
That means the INCREASE in the rate is 50 cars per day.<br>
And that means the PERCENT INCREASE in the rate is<br>
{{{(50/20)*100}}} = 250%.<br>
The new rate is 350% OF the old rate; but it is 250% MORE THAN the old rate.<br>
