Percent of earnings that go to school = 80%
Percent of earnings that was spent on the fundraiser cost = 20%
Last year earnings were= $4000
80% of 4000 went to school which is =

20% of 4000 =
went to costs.
a:
As given, this year, they want $4,000 to go directly to the school.
So let the earnings this year be represented by = x
As, 80% of the earnings go to school, so 80% of x = 4000



Hence, this year their earnings should be $5000 so that 80% of it which is $4000 will go to school. And 20% which is $1000 will go to costs.
Or we can say last year they earned $4000, so this year they need to earn $1000 more.
b:
The total amount they need to earn this year is $5000.
4c + 4t + 3s = total number of legs
example : Lets say u have 3 chairs (c) and 2 tables (t) and 4 stools (s)...
4c + 4t + 3s =
4(3) + 4(2) + 3(4) =
12 + 8 + 12 = 32 legs...then u would have 32 legs
If by next to you mean across from, it could be a parallelogram.
