To get the percent of increase, we will follow these steps:
1- get the difference between the two numbers:
difference = 1.8 - 1.2 = 0.6
2- divide the difference from step one by the original number (the number before the increase) and then multiply the quotient by 100 to get the percent as follows:
% of increase = (0.6 / 1.2) * 100 = 50%
Based on the above calculations, the percent of increase in the amount of iron is 50%
0-300-150=-450 feet
-450 feet is the whale’s elevation

After you (correctly) answered part-2, you knew the total bill . . .
(13.75 + 5%) + 15% on top of that.
(13.75) + (0.69) + (2.17) = $16.60 .
If they split the bill equally, each would pay (1/2) (16.60) = $8.30 .
But Arif wants to pay $3 more than Keisha.
Just take $1.50 away from Keisha's half (leave $6.80),
and add it on to Arif's half (make it $9.80). Then their
total is the same, but his share is $3 more than her share.
$9.80 + $6.80 = $16.60
$ 9.80 - $6.80 = $ 3.00 .
