We need to first convert everything to the same units. Let's change it to seconds. There are 60 seconds in a minute, so 63 minutes is 63 * 60 = 3780 seconds and 15 minutes, 45 seconds is 15 * 60 + 45 = 945 seconds.
Now, in order to find how many times as fast the rate going up was than the rate going down was, we divide the ascending rate by the descending rate:
Yeah so basically www is the total amount of dollars they have to buy 555 tickets. And each ticket costs $151,515, so like it's the cost per ticket times the amount of tickets to get the total amount of dollars
The variable 'a' represents how much Arthur saves. Because D'John saves $8 per week (7 days), he saves $56. Arthur saves four times more than D'John so $56*4 equals Arthur's total savings for the week; $224.
a=$8(7)*4
a=$56*4
a=$224
