3 of 4 is not the correct way of writing a ratio.
A tenth is the number that occurs after the decimal
If the number after the tenth is five or higher, then you round up
If the number after the tenth if four or lower, then the tenth stays the same value as it is
In this case, the Ume after the tenth is exactly four, so the value of the tenth stays the same
So your answer is 478.5
26, 25, 14, 13, 8, 3 descending order greatest to least
y = total snow accumulated
x = hours
the ground has 0.2 inches of snow before the data starts
y = 1.5x+0.2
0 hours = x = 0, so y = 0.2 inches
after 9 hours, we predict that 13.7 inches of snow will have accumulated
y = 1.5(9)+0.2 = 13.7
72*24=1728
1728+16=1744
now u have to deal with the 30 minutes. since its less than an hour, half actually itl be .5
1744.5
