A bag containing 15 ounces of mixed nuts contains 40% cashews. Liam adds 45 ounces of mixed nuts containing 60% cashews in the bag. What percent of the mixed nuts in the bag is cashews? A.27
B.33
C.45
D.55

The answer is D. 55%

40% cashews in 15 ounces = 40/100 × 15 = 600/100 = 6 ounces of cashew

60% cashew in 45 ounces = 60/100 × 45 = 2700/100 = 27 ounce of cashew

total weight of the mixed nuts = 15 + 45 = 60 ounces

total weight of cashew = 27 + 6 = 33 ounces

% of cashew in the 60 ounce bag = 33/60 × 100 = 3300/60 = 55%

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
