Mr. B is going to the movies with his mom, dad, and sister this weekend. His budget is $50. Each snack at the movies costs $4.50. He already spent $8 on each of the movie tickets. How many snacks can Mr. B buy?
Mr. B can buy four movie snacks.
$8 * 4 movie tickets + $4.50 * x < $50
$32 + $4.50x < $50
$4.50x < $18
x < 4
Evaluate the following function:
f(x) = 3x2 - 2x + 1
when x = 0
f(0) = 1
