Kelly works at an electronics store.    she is required to sell at least 12 items each month.    she makes a commission of $100 for each laptop and $80 for each smart phone. kelly wants to make more than $1000 for the month.    let x represent the number of laptops sold and y represents the number of smart phones sold.    determine which system of inequalities represents the situation.

x + y < 12 and 100x + 80y ≤ 1000
x + y ≥12 and 100x + 80y > 1000
x + y > 12 and 100x + 80y ≥ 1000
x + y ≤12 and 100x + 80y < 1000

if this is really you s much. i only have 3 points left and i have 2 questions to ask

your answer would be 10x - 1

it has changed from the width and the height.

step-by-step explanation:

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
