X+20 because x= origanal amount +20 more
Step-by-step explanation:
Perimeter of swimming pool = 2(l + w)
2(24 + 12)
2(36)
72
Perimeter of walkway = 2(l + w)
2(4c + 4w) [ Since it is saying all side]
8c + 8w
Expression = 72 + 8c + 8w
The sub is now 550 feet below sea level
Answer:
C. 70+20
Step-by-step explanation:
The percentage in increase can be calculated as follows:
% of increase = (difference between new and old amounts / old value) *100
For Dario:
difference in values = 413 - 350 = 63
% of increase = (63/350)*100 = 18%
For Monica:
difference in values = 270 - 225 = 45
% of increase = 20%
Therefore,
Monica has higher percent of increase.
The difference in percents = 20% - 18% = 2%
