3. 1. The 20 students on the math team want to raise $490 to buy practice books.
They have already raised $220. If each student raises the same amount, how
much more money must each student raise?

Each student must raise $13.50

Step-by-step explanation:

490-220=270 left to raise

270÷20=13.50

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

3 1/3 x 2 3/5 = 8 2/3

step-by-step explanation:

just multiply the first number by the second number to get your answer.
