Answer:
10 years old
Step-by-step explanation:
Let's say the age of the younger sister is x. Then the age of the older sister must be x + 2 because the ages are consecutive <em>even</em> numbers.
"Twice the age of the youngest exceeds the oldest by 8" means that we multiply x by 2 and set that equal to (x + 2) + 8:
2x = (x + 2) + 8
2x = x + 10
x = 10
So, the youngest sister is 10 years old.
Each roast is 7.9 lbs so you multiply that by 3.
7.9x3=23.7
now add 1.4
23.7+1.4=25.1
the round of beef weighed 25.1 pounds
You would need to use a calculator.
1 11/16 = 27/16 = 1.6875
Now multiply 100 to it to make it a percentage:
1.6875 x 100 = 168.75
So your answer is 168.75 %
