Amom bought her kids 3 cartons of milk for $1.25 each and 6 doughnuts. the total cost was $6.90. write an equation to determine the cost of a doughnut.

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

if x decreases by 4 then y increases by 10
