Answer:
1400
Step-by-step explanation:
3.5% of listeners rated the song as 1 star
49 listeners rated the song as 1 star
49 listeners = 3.5% of listeners
we want to find 100% of listeners. we can do this by multiplying both sides of the equation by 100/3.5, getting one side to 100% and the other to what it is equal to
49 * 100/3.5 listeners = 100% of listeners = 1400
Answer:
50 pounds
Step-by-step explanation:
we can use the equation 60+80/100x=1(x+50)
we get 80/100 x because the gummy candies are 80 cents or 80/100x
we get 60 from multiplying 1.20$ x 50 = 60
solve:
60+80/100x = x+50
60 = x-80/100x+50
60-50 = 20/100x
10 = 20/100x
x= 10 x 100/20 = 10x5= 50 pounds
Learn this and it can answer all ur percent problems
percent formula : is/of = %/100
36 is 75% of what number...
is = 36
% = 75
of = x.....because that is what u are looking for.
now sub into the percent formula
is/of = %/100
36/x = 75/100
cross multiply because this is a proportion
75x = 36(100)
75x = 3600
x = 3600/75
x = 48
so 36 is 75% of 48
