its an inequality eqution, i already know he can spend 30 or less on the boook

30 > 4x + 2 and 6 books

step-by-step explanation:

30 > 4x + 2

30 > 4x + 2

28 > 4x

7 > x

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
