Question

. Winston needs at least 80 signatures from students in his school before he can run for class president. He has 23 signatures already. He and two of his friends plan to get the remaining signatures during lunch. If each person gets the same number of signatures, which inequality can Winston use to determine the minimum number of signatures each person should get so he can run for class president?
A. 3x + 80 > 23 C. 3x + 23 > 80
B. 3x + 80 < 23 D.3x + 23 < 80

Answer 1

Winston needs at least 80 signatures. Let $y$ be the number of signatures Winston manages to obtain. Then $y>80$.

He and 2 of his friends obtain $x$ number of signatures.

Then $y=3x+23$.

Or, the required inequality is

$3x+23>80$

Correct choice is (C).

Answer 2

B: 3x + 80 < 23 is the answer
