Y= 80.55% approximately, 80.6% rounded up
Calculations:
The percent (percentage) of a given number p/q can be found, for the most part, without a calculator by a slight change in the notation:
y=the number 29/36 expressed as a percent becomes
y=[29(2.7777777778 approx.)]/[36(2.7777777778 approx.)]
y=0.8055 approx. (Express the decimal numeral as a percent)
y=0.8055(100)
y=
80.55% approx., which is 80.6% rounded up to the nearest tenth percent
We have 4 people in our home
so total bought 360 pounds of hamburger
each ate 2/3 pound every day
so 360-(amount eaten per day) times (number of days)=0 (0 because we want it to be gone)
number of days=x unknown
amount eaten per day=(number of people) times (amount eaten per person per day)
amount eaten per day=4 times 2/3 lb=8/3
360-8/3 times x=0
360-8/3x=0
add 8/3x to both sides
360=8/3x
multiply both sides by 3/8
1080/8=x
135=x
it would take 135 days or about 4 months or 1/3 year, assuming that my family doesn't get tired of it and that my reletives don't visit and take a whole bunch to bring home.
4 people takes 135 days
The answer would be C) 1235.
