Answer:
14.6°C
Step-by-step explanation:
Method 1
Higher value - lower value
12.2°C - (-2.4°C) *two negatives make a positive
12.2 + 2.4
14.6°C
Method 2
-2.4°C to 0°C = 2.4 increase (+2.4°C)
0°C to 12.2°C = 12.2 increase (+12.2°C)
Total change = 12.2 + 2.4= 14.6°C

Answer:
Greenland offers the lowest unit rate, dollars per pound
Step-by-step explanation:
For McCoy, $4.5 = 5 pounds
Therefore $1 = 5pounds/4.5= 1.11 pounds
1 pound= 1/1.11= $0.9009
For Eat smart
$3=2 pounds
Therefore $1=2pounds/3 = 0.667 pounds
1 pound = 1/0.667= $1.499
For Greenland
$1/5= 1/4 pounds
$0.2=0.25 pounds
$1= 1.25 pounds
Therefore 1 pound= 1/1.25= $0.8
For Mother Nature
$0.95= 1 pound
Therefore Greenland offers the lowest unit rate at $0.8 per pound
Percentages are parts of 100, so to convert 0.8% to a decimal, we just divide 0.8 by 100.
0.8 / 100 = 0.008
Dividing by 100 is the same as moving the decimal place two times to the left.
