Two eighth-grade classes are selling raffle tickets to raise money. One class is selling tickets for $4.80 each and has already raised $250.
The other class is selling tickets for $4.00 each and has already raised $215.
Which equation can be used to find t, the number of tickets each class needs to sell so that the total amount raised is the same for both classes?

answer choices :

4t + 250 = 4.80t + 215

250t + 4.80 4t + 215

4t +250=4.80t+215

Step-by-step explanation:

because 1.2 isnt half of 6 duh

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
