D. $3.90

B. $0.78

Step-by-step explanation:

Constant of proportionality = 0.78/1 = 1.56/2 = 0.78

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

rounding to the nearest thousandth would be 452,000
