Answer:
35 calories
Step-by-step explanation:
create a proportion and solve.
30/150= 7/x
There are 16 ounces in a pound, so 28 pounds is 448 ounces. Divide 448 by 8 which equals 56 ounces of dog food.
Let that certain number be 'n'
50% (n) = 39
50% ⇒ 0.5
0.5 (n) = 39
Divide both sides by 0.5
0.5n = 39
/0.5 /0.5
n = 78.
So that certain number is actually <em><u>78! :)</u></em>
CROSS CHECK:
50% of 78
0.5 × 78
= 39
Hope this helps! :)
