Question

I just need help on #21 please.

Answer 1

From the way I understand the question it would seem that a value of 50 or above is acceptable so I wrote the inequality as y \geq 12x+5 to represent the equation and I simply went up in the possible variables of (x)

The closest answer to 50 that I obtained was 53 because x=4 by simply substituting values in. With this $y \geq 12(4)+5$ which goes onto $y \geq 48+5$ which ends up as $y \geq53$
