Answer: 24 band posters should be sold
Step-by-step explanation:
First take the expression down to its simplest form;
= 5:4
Assume she sells 30 movie posters, her movies posters drop to;
= 100 - 30
= 70 movie posters
We need a number of band posters remaining that will give a ratio of 5:4 with movie posters.
In fraction form, the number of movie posters is;
= 5/9 because 9 would be the total number of both movie posters and band posters.
Create an expression to find the total number of posters if 70 are movie posters;
5/9x = 70
x = 70 ÷ 5/9
x = 126 posters
Number of band posters that should be left are;
= 126 - 70
= 56
Number of band posters that should be sold;
= 80 - 56
= 24 posters
<em>The new ratio would be 70:56.</em>

Your answer in standard form would be 5+31i
Answer:
0
Step-by-step explanation:
The first equation is for when t = 8.
The second equation is for when t = 10.
The third equation is for all other values of t.
For t = 2, we use the third equation.
f(t) = t² − 3t + 2
f(2) = 2² − 3(2) + 2
f(2) = 4 − 6 + 2
f(2) = 0
